【计】大功率半导体器件
双语例句
- To obtain a large capacity, a transformer with multiple secondary windings is used. Because the current control method is combined with the technique of phase-shifted SPWM, the power semiconductor device with lower switching frequency and larger capacity can be applied.
采用变压器二次侧多绕组的拓扑结构与载波移相SPWM的电流控制方法，能够用较低开关频率较高压的大电流功率器件来实现高压大容量电抗器。
