栅控整流器
摘要：
本实用新型是一种栅控整流器，该栅控整流器包含一线电压极性检测电路、一固定电压源、一驱动电路与一栅控晶体管。该线电压极性检测电路检测线电压的极性且控制该驱动电路以导通或截止该栅控晶体管。该栅控晶体管可为一金属氧化物半导体场效应晶体管具有一栅极、一源极与一漏极或一绝缘栅双极晶体管具有一栅极、一发射极与一集电极。该固定电压源由外部电路提供或感应且被参考至该金属氧化物半导体场效应晶体管的该源极或该绝缘栅双极晶体管的该发射极。由于较低的导通损失，此栅控整流器可被应用于整流电路以提高整流效率从而克服传统的二极管整流器通常苦于较高的导通损失的缺点。
摘要（英）：

The utility model relates to a gate-controlled rectifier, which comprises a line voltage polarity detection circuit, a fixed voltage source, a drive circuit and a gate-controlled transistor. The line voltage polarity detection circuit detects the polarity of line voltage and controls the drive circuit to conduct or cut off the gate-controlled transistor. The gate-controlled transistor can be a metal oxide semiconductor field-effect transistor provided with a gate, a source and a drain or an insulated-gate bipolar transistor provided with a gate, an emitter and a collector. The fixed voltage source is provided or induced by an external circuit and referred to the source of the metal oxide semiconductor field-effect transistor or the emitter of the insulated-gate bipolar transistor. Because of low conduction loss, the gate-controlled rectifier can be applied in a rectification circuit in order to increase the rectification efficiency, and overcomes the defects of the high conduction loss of the conventional diode rectifier.
