The Research of High Frequency Soft Switching Power Supply Control Circuit

This thesis mainly introduces a kind of soft switching technology which is named as phase-shifted full-bridge zero voltage PWM control technology, the basic working principle of power factor correction Boost converter and an control chip UC3854 commonly used by Boost converter. The paper designs an control circuit of Boost converter based on UC3854, moreover, it puts forward an improved PFC circuit.
