The electric power electronic technology development, specially high efficiency component IGBT and the MOSFET rapid development, enhances the switching power supply operating frequency to the quite high level, enable it to have the high stability and high performance-price ratio and so on the characteristic. One of switching power supply technology main uses is serves for the information industries. The information technology development also set a higher request to the power source technology, thus promoted the switching power supply technology development. Switching power supply in the power adjustment control work in the off state, with low power consumption, high efficiency, wide voltage range, low temperature rise, and other outstanding advantages of small size, the communication equipment, CNC equipment, Instrumentation, video audio, home appliances so widely used in electronic circuits. High frequency converter switching power supply so many forms of commonly used with push-pull converter, full bridge, half bridge, single-ended forward and the form of single-ended flyback.This paper is base
