This paper presents sliding mode pulse width modulation (SMPWM) control methodologies for a current- controlled inverter. Discussion begins with circuit analysis, proper references, and design of sliding surfaces. Based on this formulation, two novel approaches adopt sliding mode concept are proposed to make the system tracking selected references. Three-phase currents and the neutral point voltage are controlled simultaneously. Optimization of different operational criteria is offered by SMPWM via the control of neutral point voltage. Simulations are carried out to confirm the effectiveness of proposed control algorithms.
