Claims (1)
、平滑コンデンサに蓄えられている電荷をＧＴＯ
素子を使つて、強制急放電させ、また、インバー
タ運転中、回生状態での過電圧を強制急放電させ
て抑制することを特徴としたインバータの急放電
回路。 In a voltage source inverter device, when the power is turned off, the charge stored in the smoothing capacitor is transferred to the GTO.
A rapid discharge circuit for an inverter, which uses an element to cause a forced sudden discharge, and suppresses overvoltage in a regenerative state during inverter operation by forcing a sudden discharge.
