Frequency converters with active rectifiers (FC-AR) are now used in rolling mill electric drives. Modern control systems of ARs are not adapted to voltage sags in power supply systems, which leads to converter tripping. The known methods of ensuring AR operation stability, such as kinetic buffering, correction signals based on negative sequence voltage and others, do not eliminate these emergency trips. As an additional measure the paper proposes the method of voltage sag compensation by using static var compensators (SVC) of electric arc furnaces (EAF) for parallel operation of frequency conv

High power and medium voltage (MV) applications need Controlled rectifiers such as 12-pulse converters, because of the high reliability, low complexity, robustness and low power losses. But having the drawback of harmonics generation causes power quality problem. Power quality can be improved with passive filters but having disadvantages such as dependency on the source impedances, parallel and series resonance, aging of passive components. Active power filtering (APF) is used as compensation technique in order to improve thepower quality at the line side. Hence APF becomes a promising compens

Hybrid HVDC systems have been proposed as an alternative for nominal VSC-Based HVDC for offshore applications. Hybrid HVDC systems consist of an offshore power station composed of the connection of high-power diode rectifiers in series with a fractional power VSC-HVDC. This hybrid configuration allows large power transfer from offshore sites, with the added robustness, simplicity and efficiency of uncontrolled rectifiers.

In an electrical power grid, for an equal amount of usable power transmitted, a load with a coffee power factor draws more current than a load with a small power factor. The higher currents increase the loss of energy in the distribution network and require larger wires and other equipment. Due to the costs of larger equipment and waste energy, electrical utilities will usually charge a much higher cost to industrial or commercial customers where a low power factor is present. Low-power factor linear loads (such as induction motors) are often corrected with a passive condenser or inductor netw

The implementation of electric power in aircraft system increases the use of different kinds of power electronic converters such as AC/DC rectifiers, DC/AC inverters and DC/DC choppers in the system. The incursion of numerous power electronic devices leads to complex network and also causes power quality and stability issues. The current harmonics may cause unbalance in the aircraft electric power system and severe voltage distortion. Thus, the active filters can compensate the harmonics, improves the power factor and work as a reactive power compensator, thus in turn afford power quality enha

Power quality is the most significant factor of power sector. The end user equipment such as induction motor, inverters, rectifiers inject harmonics into power system that influences the quality of power delivered. The presence of harmonics forces the use of instantaneous reactive power theory to calculate instantaneous power that helps in finding the compensating currents to eliminate harmonics.

In view of the fact that active power and reactive power have coupling relation, a novel vector decoupling control strategy is presented for three-phase voltage source PWM rectifier. In the paper, the power control mathematical mode of the PWM rectifier is deduced based on the mathematical model of rectifier in synchronous d-q rotating coordinates, and a new voltage feed forward decoupling compensation control strategy is proposed. The simulation results show that the voltage and current of the three-phase PWM rectifier have better respond preference, the current aberrance is smaller and the v

This paper presents a CMOS active rectifier with a time-domain technique to enhance power efficiency. A delay compensation circuit was designed using a time-domain technique. It converts the delay buffer’s delay time to a voltage value. The voltage is able to control on/off time in the comparator for variable input voltage. This circuit is designed in 0.18 m CMOS process. The input voltage range is from 2 V to 3.8 V with the output voltage from 1.8 V to 3.6 V. The efficiency can be maintained at more than 83% when the load is from 100 Ω to 1300 Ω for 3.3 V input voltage. The maximum efficiency

Abstract The article discusses the universal current sensor fault detection and compensation mechanism, which can be applied in three-phase power electronics (PE) symmetrical system. The mechanism is based on the assumption that a symmetrical system can be described using different components in the stationary reference frame. The solution given in article as a Cri-base detector was tested in electrical drives with induction motors (IMs) and permanent magnet synchronous motors (PMSMs). This study also proves that the same algorithm can work stable in active rectifier systems. Such an applicati

Rectifier is a non-linier load that causes harmonic distortion in the power system. Pulse-width modulation (PWM) method is an effective method in pressing the magnitude of harmonics in a rectifier application, it provides an almost sinusoidal input current. However, the variation of loads that supplied by a rectifier cause the harmonics that arise can still beyond the applicable standard. The amount of harmonics in the operating range of a rectifier need to be identified to determine the filter on the input side. In this research article, 3-phase PWM rectifier was designed with hysteresis curr

This paper proposes the modeling and design of a controller for an inductive power transfer (IPT) system with a semi-bridgeless active rectifier (S-BAR). This system consists of a double-sided Inductor-Capacitor-Capacitor (LCC) compensation network and an S-BAR, and maintains a constant output voltage under load variation through the operation of the rectifier switches. Accurate modeling is essential to design a controller with good performance. However, most of the researches on S-BAR have focused on the control scheme for the rectifier switches and steady-state analysis. Therefore, modeling

Abstract In response to the problem of prolonged low voltage at the end of distribution grids, a voltage compensation method for multi-feeder distribution networks based on a unified power quality controller (UPQC) with PV injection is proposed in this paper. In the proposed scheme, two series inverters, a single parallel rectifier and photovoltaic (PV) system are flexibly interconnected via DC bus. The voltage attenuation can be compensated by the two series inverter, and the parallel rectifier is capable of supplying energy to the DC side of the two series inverters on adjacent AC feeders. M
