| 摘 要： | 为实现一种结构简单、可靠性高的三相软开关逆变器,提出一种新型辅助谐振变换极软开关逆变器的拓扑结构,在电路中采用高频变压器来均分直流电源电压,避免了使用大电容,没有中性点电位的变化问题,可靠地实现了主开关器件的零电压开通和辅助开关器件的零电流关断,二极管的反向恢复损耗也被有效降低,而且拓扑结构中设置了变压器的去磁复位电路,可靠地保护了辅助开关器件.对其工作原理进行分析,给出不同工作模式下的等效电路图和回路的参数设计原则.制作一个1 kW的实验样机,通过实验结果验证该软开关逆变器的有效性.

| Abstract: | A novel auxiliary resonant commutated pole soft-switching inverter was proposed to realize a three-phase soft-switching inverter which has a simple topology and high reliability.A high frequency transformer was used to divide the voltage in the DC side in half.It avoided the bulk capacitor and there was no center tap potential variation problem,which realized reliably zero-voltage turn-on of main switches and zero-current turn-off of auxiliary switches,reduced reverse recovery losses of diodes.Furthermore,a... |
