| 摘 要： | 设计了一种新型的零电压、零电流倍流整流电阻焊逆变电源,采用移相控制实现零电压、零电流开关全桥变换,其中超前桥臂实现零电压开通,滞后桥臂实现零电流关断。变压器二次侧采用一种单线圈双电感双管全波整流电路,整流二极管实现零电流自然关断,逆变器所有的功率器件都工作在软开关状态,降低了功率器件的应力和开关损耗,提高了弧焊逆变器的电磁兼容性能力,突出了逆变电源节能、体积小、质量轻、响应速度快的优点,特别适合大功率场合。

| Abstract: | A new resistance welding inverter with zero-voltage and zero-current switching(ZVZCS-PWM was designed.The zero-voltage turn on was achieved for the leading-leg of the converter,and zero-current turn-off was achieved for the lagging-leg.A single line and double inductance commute circuit was used.The rectifier diodes in the secondary side were turned off naturally.All the power semiconductors in the converter were operated with soft-switching condition.Hence the switching stresses,losses and interferes were ... |
