Abstract
A non-isolated resonant gate drive circuit includes a PMOS drive network, an NMOS clamping circuit and an inductor. The PMOS drive network and the NMOS clamping circuit are connected in parallel to two terminals of the inductor. Input signals of the PMOS drive network are provided by a function generator connected to a drive chip, drive signals are output via an output port vand an output port vafter the input signals are processed by the PMOS drive network, the NMOS clamping circuit and the inductor, the NMOS clamping circuit is used for controlling the state of the output port vand the output port vto change, and the inductor forms LC resonance together with a gate capacitor Cand a gate capacitor Cin the NMOS clamping circuit to recover energy in a process of turning off the drive circuit.
