Abstract:

Power Electronics is widely used in bioscience and medical instruments such as Electrosurgical Units, MRI and X-ray. An advance development in switch mode power supply leads to a new design topology of DC to DC convertor for Electrosurgical Systems. The new designed system has a capacity to produce high efficient output power with high resonance, this improves the performance of the surgery operation. This paper reports a Buck-Boost topology DC to DC (Flyback) converter with high power switching. The simulation results show an improved performance when compared to the existing system.

Abstract:

In this study will simulate steady state of Digital Down Convertor (DDC) for GSM signal with a narrow frequency range. The MATLAB model that is described in this article simulates the work of the TIGC4016 Quad Digital Down Converter. This converter is used for digital mixing (down conversion) of signals, narrow band low-pass filtering and decimation. To implementation of the model, we use high sample-rate (69,333 MSPS) bandpass signal. The result contains low sample-rate (270.83 KSPS) baseband signal, thus facilitating the demodulation process.

Abstract:

The article presents the research results on a device for automatic measurement of the temperature stability of the output characteristics of voltage-to-frequency converters. The device can be used to measure mechanical stresses in the ship's hull. The main source of information on the state of the mechanical stress on the hull of the ship is the integrated monitoring system. Monitoring methods are based on measuring the frequency of the output signals from the sensors based on strain gages, which have a wide scatter of values for parameters and characteristics and depend on external factors. A possible solution to this problem is to use a device that would convert the analog sensor signal into a more noise-immune signal of another type, for example, voltage-to-frequency converter. It is for such systems based on synchronous integrated converters that the authors have developed a device for automatic measurement of the temperature stability of the output characteristics of frequency converters. Such device can measure the thermal stability of the convertor automatically, which makes it possible to analyze the effect of temperature on the output characteristics of the converter and to experimentally study the sensors in a wide range of operating temperatures (from room temperature to 70℃). The study of the thermal stability of the characteristics of such sensors made it possible to confirm the quality of its electronic components and to determine which parameters need to be adjusted. The device is a set of units, one of them being a control circuit based on the ATmega-16 RISC microcontroller. This design and the developed algorithm for the device operation makes it possible to determine the output frequency with a high accuracy (with a measurement time of 1 sec, the accuracy reaches 0.05%). The developed device allows finding the ways to increase the thermal stability of mechanical stress sensors based on integral converters.

Abstract:

A new management approach for the reactive-power injections of Voltage supply Converters in High Voltage DC (VSC-HVDC) multi-terminal Systems to enhance grid transient stability. A reactive-power supplementary signal is provided for each convertor. Its worth is proportional to the frequency deviation of its consequent AC bus with admiration to the weighed-average frequency of the multiterminal system stations. The hope is to extend (decrease) the magnetism torsion of generators close to those terminals during which the frequency is superior to (below) the weighed-average frequency used. The AC frequency for all VSC stations is ever more accessible regionally for synchronization functions and will be utilized by a central controller. Simulations are allotted victimization PSS/E and therefore the outcome have revealed that transient stability is enlarged victimization this approach. Since this approach uses world capability of all VSC stations, the collision of the communication delays has been analyzed, concluding that the depressing consequence is modest, for realistic latency values.

Abstract:

This paper presented a low-power Direct Digital Frequency Synthesizer (DDFS) using non-uniform sine-weighted digital-to-analog convertor (DAC). To avoid the need for a sharp filter to generate signals near and beyond the Nyquist frequency, parallel DACs, which cause to speed relaxation in a single DAC as well, and return-to-zero (RZ) technique were used. To reduce the area and power in parallel DACs, non-uniform sine-weighted DAC design method was proposed. This technique causes to reduce power consumption in DACs up to 48.47%, and nearly the same amount of reduction in the area. Meanwhile, by modifying weights of DAC cells, Gilbert cell, the latter block in DDFS structure, was omitted. Although these proposed methods are quite frequency independent, simulations with MATLAB and Cadence in 0.18[Formula: see text][Formula: see text]m CMOS technology were used to demonstrate those. Then, the designed DDFS with 5-bit frequency resolution could generate different output sine signals with acceptable spurious free dynamic range (SFDR).

Abstract:

Modernization of the pusher electric drive of inter-stand cooling facility of sheet rolled product is an actual way to increase efficiency of rolling production. The control by the existing electric drive is accomplished by a system, comprising an asynchronous motor. Problems of automation of the facility of inter-stand cooling of sheet rolled product of JSC “Ural steel” sheetrolling shop considered. Modernization of existing system by implementation of frequency convertor with vector control proposed. To restrict the pusher movement it proposed to use induction sensors and controller SIMATIC S7-300. Algorithm of the pusher operation with induction sensors application considered. The elaborated algorithm of the pusher operation realized on the base of SIMATIC S7-300 controller. Calculation and building of load diagram and the pusher drive tachometric diagram accomplished for one cycle of its operation. Taking into account nominal data of the pusher selected motor and requirements to electric equipment, a frequency convertor with vector control was selected. Implementation ofthe system “frequency convertor – asynchronous motor” with vector control justified. The vector control enables to provide a preset pace of the motor acceleration, its complete protection against over-loading that increases considerably service life of the electric drive system as a whole. Application of frequency controlled pusher drive together with SIMATIC S7-300 controller will enable to automatize the process of the pusher operation. Implementation of the developed automation system of the pusher electric drive operation is possible also at other steel-works.The payback period of the solutions proposed within the frame of the project will be 9 months.

Abstract:

In modern wireless communications, digital information is firstly converted to analog signal by a digital-analog convertor, which is then mixed to high-frequency microwave to be transmitted through a series of devices including modulator, mixer, amplifier, filter, and antenna and is finally received by terminals via a reversed process. Although the wireless communication systems have evolved significantly over the past thirty years, the basic architecture has not been challenged. Here, we propose a method to transmit digital information directly via programmable coding metasurface. Since the coding metasurface is composed of ‘0’ and ‘1’ digital units with opposite phase responses, the digital information can be directly modulated to the metasurface with certain coding sequences and sent to space under the illumination of feeding antenna. The information, being modulated in radiation patterns of the metasurface, can be correctly received by multiple receivers distributed in different locations. This method provides a completely new architecture for wireless communications without using complicated digital-analog convertor and a series of active/passive microwave devices. We build up a prototype to validate the new architecture experimentally, which may find promising applications where information security is highly demanded.

Abstract:

In this work, an inductive wireless power transfer module powered by resonant converter is studied. The system consists of a zero voltage switching resonant converter and a rotary wireless power transmitter. The design of the rotary wireless power transmitter is presented. Simulation and experimental studies of the system confirm reliable operation of the power electronic converter with a wide range of loads. The zero voltage switching is maintained without significant adjustments in the switching frequency. This improves the system stability with variations in the air gap between transmitting and receiving modules or the magnetic coupling ratio. The studied system is suitable for powering loads placed on a rotating platform or other applications where the disadvantages of moving electrical contacts are undesirable.

This study describes the application of the techniques of stochastic modeling to random data obtained from the sea trials of the wave energy device Kaimei, and the interpretation of the results in terms of device efficiency. Two models of the power absorption system are developed and the relationships derived between them yield information on the influence of the vessel motions on the absorbed power. The theory of multiple frequency response functions is applied to the data, and it is shown that the motions of the Kaimei have a detrimental effect on its energy absorption capacity and the reasons for this are investigated.

Abstract:

This paper presents a digital MEMS gyroscope with 40[Formula: see text]/h instability variation in −40[Formula: see text]C to 85[Formula: see text]C, performing 5[Formula: see text]/h instability variation at normal temperature and 0.01% nonlinearity in the range of ±400[Formula: see text]/s. This stability was achieved by using temperature compensation for the zero-output value changed after the temperature signal. As the resonant frequency of the mechanical structure varied according to the temperature linearly, a frequency calculator was adopted to detect the temperature of the mechanical structure. And the resolution of the frequency could be up to 0.01 Hz with a 1 MHz clock frequency used, obtaining a 10 Hz bandwidth. The driving mode used a PI controller to control a VGA to maintain at a fixed effective value of the driving signal. The sensing mode contained a low noise C/V convertor and a switch demodulation, which could give the angular velocity signal to the A/D convertor. Then the output data of A/D will be compensated in the digital domain. Finally, the digital output of the gyroscope will be available through a normal SPI serial port. The whole circuit was realized on one chip with an active circuit area of 3.5 mm × 5.2 mm fabricated in a 0.35 [Formula: see text]m CMOS technology. And the MEMS structure and circuit are packaged in a 2.5 cm × 2.5 cm × 2.5 cm aluminum mold. The digital output of the gyroscope earned a noise floor of 0.0024[Formula: see text]/s.

Abstract:

This paper proposes single-layer periodic arrays of freestanding slot frequency-selective surface (FSS) as an approach to convert linearly polarized wave to circularly polarized wave. The double U-type structure is etched on a metal plate rather than a traditional print circuit board (PCB) material. It has the characteristics of broadband and could be applied to the situation of large incident angles. Numerical simulations have been carried out, and the prototype structures have been fabricated and experimentally validated. The whole thickness is only 1 mm, and the results show that 3 dB axial ratio (AR) bandwidth is 36.6% at normal incident (16.5% at ±60°). An insertion loss of under 3 dB can be achieved within the whole AR bandwidth.

Abstract:

Abstract When performing data acquisition for a Dynamic Light Scattering experiment, one of the most important aspect is the filtering and conditioning of the electrical signal. The signal is amplified first and then fed as input for the analog digital convertor. As a result a digital time series is obtained. The frequency spectrum is computed by the logical unit offering the basis for further Dynamic Light Scattering analysis methods. This paper presents a simple setup that can accomplish the signal conditioning and conversion to a digital time series.

Abstract:

AbstractVentspils International Radio Astronomy Centre (VIRAC) has two fully steerable Cassegrean System 32 and 16 m radio telescopes. After renovation and modernization program the Galactic masers, particularly CH3OH research and monitoring program became one of the most important realized on these telescopes. Both telescopes are equipped with broadband cryogenic receivers covering 4.5-8.8 GHz frequency band. Digital backend consisting from DBBC-2 (Digital Base Band Convertor developed by HAT-LAB, Italy) and FLEXBUFF (data storage system based on commercially available server system) is used for data digitalization and registration. A special program complex for spectral line data reduction and correction was developed and implemented.
