A novel scheme of low power communication power supply with high power factor and soft-switching is presented, a power factor corrector and dc/dc converter of passive lossless soft-switching is based on a ML4803 IC control. DC/DC converter introduces a novel two-transistor forward soft-switching technique, which realizes zero-voltage turn-on and turn-off, with no additional switches. a communication power supply module is developed in this paper. It has the characteristics of rapid dynamic response, high power factor, high efficiency and small bulk ect.

High Power Factor

For the existence of a large input current harmonic content and the problem of low power factor, we propose an idea using APFC technical to design high power factor switching power supply to deal with it, meanwhile, the design process of APFC circuit parameters of the various components is given. Finally, the design proved to be correct and feasible by the simulation with Saber.
