چکیده

An active current injection network for a three-phase diode rectifier is proposed. Current injection is done by using two networks: injection network and injection device. The injection network composed by a half-bridge inverter operating at high frequency and injection device is composed by three bi directional switches operating at low frequency. It also uses one inductor in order to get the desired injected current .This proposed converter offers high efficiency, high power factor and also total harmonic distortion will be reduced. Operation, analysis, simulation results are shown in this paper. Keywords— Current Injection, high power factor, three-phase rectifiers, THD

A Single-Phase Controlled Rectifier with Unity Power Factor

An approach recently introduced to correct the power factor of single-phase and three-phase diode rectifiers is extended to single-phase line-frequency phase-controlled rectifiers. First of all, the conventional circuit of the thyristor based rectifier is proposed to be modified in order to make possible the control of the DC-voltage mean value also in presence of a fully resistive behaviour of...

Power filtering method with controllable inductance for eliminating thyristor rectifier load harmonics

In this paper, we propose a Controlled Inductance Power Filter (CIPF) to solve power quality problems in industrial DC power supply systems. This method is based on the theory of magnetic potential equilibrium combined with active hybrid filter technology. Initially the system structure and filter wiring scheme are presented and the equivalent circuit is performed with the mathematical models o...

On Analysis of Front End Current of Rectifier Converter for low THD and high PF with SEPIC

Most of the power electronic equipments are operated with dc supply. For reliable and stable operation, dc supply should be regulated. The regulation can be performed using buck, boost, Cûk, Sepic, Flyback regulators. Except single phase rectifier with resistive load all other rectifiers input currents are non sinusoidal in nature. This front end current distortion of rectifier converter leads ...
