The utility model relates to a circuit, a power factor corrector and a converter. The capacitive element has its terminals coupled together by two thyristors electrically antiparallel. Discharging of the capacitive element is controlled by applying a gate current to one of the two thyristors that is in a reverse-biased state in response to a voltage stored across the terminals of the capacitive element. The reverse-biased thyristor responds to the applied gate current by passing a leakage current to discharge the stored voltage. 本公开涉及电路、功率因数校正器和转换器。电容性元件具有通过电反并联的两个晶闸管耦合在一起的其端子。通过向两个晶闸管中的、响应于跨电容性元件的端子存储的电压而处于反向偏置状态的、一个晶闸管施加栅极电流，来控制电容性元件的放电。反向偏置的晶闸管通过使泄漏电流通过，来对所施加的栅极电流进行响应，以使存储的电压放电。
