Abstract: A circuit making use of a push/pull-type control chip to drive a half-bridge inverter of dual N-MOS connects a drive circuit to a conventional half-bridge inverter circuit, and has a push/pull-type control chip having two output terminals, a drive circuit having two input terminals and two output terminals, and a half-bridge switch assembly having a first N-MOS FET and a second N-MOS FET. The two input terminals of the drive circuit are connected with the two output terminals of the push/pull control chip and controlled by the push/pull-type control chip. Each of the two N-MOS FETs of the half-bridge switch assembly has a control terminal, which is connected to one of the two output terminals of the drive circuit and driven by the drive circuit for converting a DC power source into an AC power source sent to the primary side of a transformer.
