例句
- The load current is handled directly by the controller through semiconductor switching devices.
負荷電流由調節器通過半導體開關元件直接控制。 - By using zero-voltage-transition techniques, a lossless snubber circuit has been developed to reduce the switching losses of the auxiliary switch.
本文針對輔助開關採用零電壓轉換方式以降低輔助開關損失，讓所有的主動與被動開關元件皆操作在柔性切換狀態下，提高整體效率。
