Abstract: The application provides a gate driver circuit and a multiphase intelligent power module. When a first switch unit is closed, a power supply charges a first capacitor and a second capacitor, and a first buffer provides a gate voltage for a first power transistor. The first capacitor can improve the potential of the gate of the first power transistor, so that the first power transistor is turned on; second capacitor can provide a negative turn-off voltage for the first power transistor, and can adaptively convert external voltage into voltage that can drive the power transistor. Moreover, the circuit can be realized easily and the voltage of the first power transistor is stable.

Abstract: The invention relates to a reset mechanism of the key duplication device which comprises a reset apparatus, a spindle and a body, wherein the spindle is inserted into the body and is rotatably connected to the body. Between workspace and a loading area, the body is repeatedly moveable along the spindle. The reset mechanism comprises an elastic member connected with the body. Elastic forces of the elastic member always act on the body and move the body toward the workspace. After the body is rotated to the loading area against the elastic forces of the elastic member, when a withdrawal force exceeds the elastic forces, the body automatically returns to the workspace under the influence of the elastic forces. The fewer and easier operating steps the more efficient work of the reset mechanism is, and the mechanism more conforms to the ergonomics design.
