应用了一种新颖双管正激组合变换器作为三态滞环控制电流型逆变器直流输入前级,研制了一种输出7.5 kV·A的单相航空静止变流器,将某型号飞机上三相115V/400 Hz供电系统,变换成220V/50Hz单相交流电,以满足特殊机载设备的供电要求。
A novel two-switch forward-coupled converter is applied as a three-state hysteresis control current-mode inverter DC input pre-stage. A single-phase aerostatic static converter with output of 7.5 kV · A was developed. On the three-phase 115V / 400Hz power supply system, transformed into 220V / 50Hz single-phase AC, to meet the special airborne equipment power requirements.
