Abstract—Sliding mode control scheme for the full bridge inverter was analyzed, including modeling the variable structure system, selecting the switching line and control law. To make maximum use of degrees of freedom of the full bridge inverter circuit switching device, the idea of the single polarity sine pulse width modulation (SPWM) is introduced to the sliding mode control in full bridge inverter to reduce the switching loss. Furthermore, zero forced zero sliding mode PWM is used to suppress voltage distortion caused by sliding mode surface passing zero modulation. Simulation results are given to verify the correctness and validity of implemented zero forced zero sliding mode PWM for full bridge inverter.

Index Terms—sliding mode control, full bridge inverter, variable structure system, pulse width modulation.
