Patent ID: 7157861

Claim:
A push-pull inverter circuit, being disposed between a power supply unit and a load for receiving a power signal inputted by said power supply unit and driving said load by a power conversion of said inverter circuit and said inverter circuit comprising: a transformer unit, having a power output end and a power input end, the power output end being connected to said load; a power driver unit, being connected between said power output end and said power supply unit for receiving said power signal and outputting two sets of drive signals having same frequency and opposite phase to said power input end as to constitute said inverter circuit that uses a push-pull voltage drive signal to drive the operation of said transformer unit; said power drive unit comprises a control unit and two sets of power switches, the control unit outputs two sets of drive signals having a same frequency and opposite phase, and an inductor being disposed between at least one of the power switches and said transformer unit.
