Driving method and device of semi-control type device and mixed type device

Abstract

The invention discloses a driving method and device of a semi-control type device and a mixed device, belongs to the field of electricity, and particularly relates to a driving method which is applied to a tiny non-driving dead zone or a driving dead zone of a semi-control type device of a silicon controlled rectifier and the like, a semi-control type driving device applied to a tiny non-conduction dead zone and a conduction dead zone used in the driving loop of the semi-control device of the silicon controlled rectifier and the like, and a mixed type device of the tiny non-conduction dead zone or the conduction dead zone. According to the driving method of the semi-control type device, a voltage detection switch is adopted, the input end of the voltage detection switch is connected to the two ends of the semi-control device to be driven, the voltage detection switch is connected to the driving loop of the semi-control type device in series, the potential difference of the voltage detection switch at the two ends of the semi-control type device is no larger than the conduction when the semi-control type device is at on-state voltage, and the voltage detection switch cuts off after detecting that the semi-control type device is conducted. The driving method and device of the semi-control type device and the mixed type device have the advantages that the non-driving dead zone or the driving dead zone is tiny.
