摘要
本文简单分析了2.2KW电力系统用直流操作电源移相全桥软开关拓扑结构,设计和选择了主电路的滤波电容和电感等元件,制作了软开关主电路的主要部件,包括高频变压器和谐振电感;根据设计的开关电源实际特点,选择了主功率管和次级整流二极管。
In this paper, the phase-shifted full bridge zero voltage soft switch (ZVS) topology of 2.2KW electric operation power supply is analyzed in brief. Then, parameters of filter capacitor and inductor in main circuit are designed and selected. At the same time, the high frequency transformer and the oscillatory inductor are manufactured. According to the actual characteristics of switch power supply, the power MOSFET and the second rectifier- diode are chosen. Finally, the rationality of the design is verified.
