Abstract:

An accurate stator resistance and inductance are necessary for high-performance permanent magnet synchronous motor (PMSM) control. The stator resistance and inductance can be estimated during motor standstill operation. This study proposes a standstill estimation method for the determination of dq-axis inductances and resistance of a PMSM drive system fed by a conventional voltage source inverter (VSI). The proposed method estimates both inductance and the rotor's position using the same algorithm, and knowledge of its initial position is not required. The d- and q-axis inductances were estima

Abstract:

In traditional 3-pin High-Voltage (HV) power MOSFET (MOSFET) packages, the hard-switching transition speed is limited by the package source-inductance because the MOSFET drain current and gate current both share a path through the same package source inductance. The details of this mechanism are discussed and the resulting additional switching power loss caused by it is both measured and simulated. Proposed innovative “Source-Sense” packages split the two currents into separate paths by adding separate source-pin for Kelvin-type driver connection to gate-source on the chip, thus completely eli

Achieving high-power density is a challenge in the presence of stringent specifications on temperature rise and switching noise. Integration of the direct-bond-copper module with PCB mother board was found to be the right approach to achieve 220-W/in3 power density, 2-kW output power, and 48.9°C junction-temperature rise. The reduced layout inductance (2.89 nH) at the source and the negative coupling between source and drain layout inductances suppressed turn-off noise. The prototyped dc-dc boost converter switched between 400 kHz to 1 MHz without self-turn-on problems.

Abstract:

Planar spiral coils are used as inductors in radio frequency (RF) microelectronic integrated circuits (IC’s) and as antennas in both radio frequency identification (RFID) and telemetry systems.

They yield the direct current (DC) inductance, which is considered as a good approximation for inductors in RF IC’s up to the GHz range. In principle, these formulae can simplify coil design considerably. But a recent c

The present work aims at comparing different coupling coils by taking into account sources of uncertainty for static inductive power-transfer (SIPT) systems.

In practice, however, there are inevitable parasitic inductances, which result in the increase of switching losses.

Abstract:

This work presents a series representation for the mutual inductance of two coaxial pancake coils which remains accurate in non-quasi-static regime under the hypothesis that the current in the source coil is uniformly distributed. Making use of Gegenbauer’s addition theorem and a term-by-term analytical integration, the mutual inductance between two generic turns belonging to distinct coils is expressed as a sum of spherical Hankel functions with algebraic coefficients. The accuracy and efficiency of the resulting expression is proved through pertinent numerical examples.

Abstract:

An algorithm for controlling the modules of a power supply source of vacuum electric furnaces intended for growing artificial monocrystals of leucosapphire according to the Kyropoulos method is considered. Since the modules from which a source with the required capacity is assembled by connecting them in parallel are not exactly identical with one another, and so are the current conducting buses used to interconnect them, a situation may occur in which some of the modules are underloaded, while others are overloaded. Therefore, in addition to stabilizing the total power produced by the source,

Abstract:

The hexagram multilevel converter (HMC) is composed of six conventional two-level voltage source converters (VSCs), where each VSC module is connected to a string of PV arrays. The VSC modules are connected through inductors, which are essential to minimize the circulating current. Selecting inductors with suitable inductance is no simple process, where the inductance value should be large to minimize the circulating current as well as small to reduce an extra voltage drop. This paper analyzes the utilization of a multiwinding (e.g., two, three, and six windings) coupled inductor to interconne

Abstract:

Half-bridge modules with integrated GaN high electron mobility transistors (HEMTs) and driver dies were designed and fabricated in this research. Our design uses flip-chip technology for fabrication, instead of more generally applied wire bonding, to reduce parasitic inductance in both the driver-gate and drain-source loops. Modules were prepared using both methods and the double-pulse test was applied to evaluate and compare their switching characteristics. The gate voltage (Vgs) waveform of the flip-chip module showed no overshoot during the turn-on period, and a small oscillation during the

This paper discusses a simple method for controlling an LLC resonant DC-DC converter using a state space trajectory based on a linear combination of the voltage across the capacitor and the current through the inductance in the series resonant tank. An analysis of the converter using the state plane technique for the continuous current operation mode is proposed. The output, control and load characteristics of the converter, required for its design and application, are built for the different inductance ratios.

Series–series (SS) wireless power transfer (WPT) systems are used in many applications because of their simple circuit structure. Compared with higher-order complex compensation topology, they are suitable for more demanding applications, such as rail trams with high power requirements but limited space for the coupling mechanism. However, the characteristics of their voltage source also put forward higher requirements for the control strategy. Improving the dynamic response performance of an SS compensation WPT system without any communication between the primary and secondary sides is the ke

Abstract:

In the current source inverter (CSI)−fed inductor motor (IM) drive system, DC−bus inductance and AC−filter capacitance have a direct impact on the dynamic response speed, power quality and power density. In addition, due to the addition of filter capacitors, the mathematical model formed by the IM and capacitor is a third−order system, which increases the difficulty of parameter tuning for the control loop. To solve the above problems in the CSI, a DC−bus inductance design method based on current response speed and the ripple of the DC−link current and an AC−filter capacitance design method ba

Abstract:

A technique for tunable filters with low insertion loss and narrow bandwidth is proposed in the form of comb-line structure. Both resonant capacitor with pin-diodes and resonant inductance in the tunable filter were analyzed and the main source of insertion loss was obtained. A series of filters with same pin-diodes, center frequency, absolute bandwidth and low return loss was simulated. The results showed that, by changing the values of the resonant capacitor and inductance, insertion loss of the filter can be greatly restricted. This technique will allow the design of tunable LC filters with

This paper presents an auxiliary passive circuit and control design for wireless power transfer (WPT) systems in DC microgrids to achieve optimal power transfer efficiency while maintain accurate output voltage regulation. An auxiliary inductance is added at the transmitter resonator to form a current sink to ensure zero voltage switching (ZVS) of the primary-side full-bridge inverter with even extremely light load conditions. Moreover, an adaptive proportional–integral (PI) controller is adopted to track the output voltage references by regulating the phase shift angle of the phase shift cont

In this research has been developed the application of flat coil as vibration sensor for early detection of earthquake. The flat coil is a very thin wire winding and acts as an inductor. This flat coil along with the capacitor constructs an oscillator which generates frequencies depending on the value of inductance and capacitance. This oscillator is called the LC oscillator. The flat coil inductance depends on the distance of the metal object in front of the flat coil. If the inductance changes, the frequency will change as well.

The equivalent inductance of three-phase induction motors is experimentally investigated in this paper, with particular reference to the frequency range from 1 kHz to 20 kHz, typical for the switching frequency in inverter-fed electrical drives. The equivalent inductance is a basic parameter when determining the inverter-motor current distortion introduced by switching modulation, such as rms of current ripple, peak-to-peak current ripple amplitude, total harmonic distortion (THD), and synthesis of the optimal PWM strategy to minimize the THD itself.
