Abstract :
A favourable method of converting power from a three-phase AC input voltage source to an isolated DC voltage output source is presented. It improves the power factor at the input of the converter. The circuits are based on inductive energy storage and only use a single transistor to switch the transformer(s). A special control algorithm for the IGBT is not required as the input voltage and input current of the power factor conditioner are proportional. It is possible to determine the maximum transistor voltage by dimensioning the circuit parameters. The output voltage is isolated from the input voltage
