The plating equipment, water treatment system, electrolysis facility, etc need the high current and high power rectifier for their original purposes. So the paper investigates the applicable types of rectifiers and carries out their comparisons, and also suggest the practical design guidelines for a suitable candidate rectifier for low voltage high current high power applications.

In this paper, the PC power supply is studied from the point of system stability The power stage model of a multiple output forward converter with weighted voltage mode control is derived, including all the major parasitic components, and the small signal model is also derived Deterimination of the weighting factors and a design procedure for the loop compensation are presented. Finally, the model is verified through the simulation of three output forward converter with SABER.

In this paper, we propose a new single-stage isolated switching power supply. The proposed converter reduces the diode conduction loss and offer both the high input Power factor and the direction conversion from the ac line to a dc output voltage.<br/> This paper present the Operational principle, analysis and control and experimental results of a 100W prototype.
