A Novel Control Strategy for High-Performance Single-Phase Inverters

In this paper, a rather simple controller without time delay is proposed for single-phase PWM inverters to achieve good output voltage tracking, zero steady-state error, very low output impedance and audio susceptibility. To enhance the design efficiency, closed form design rules for the proposed standard module controller are further derived. The required capacitance value of the filter is also derived to minimize the size, cost and losses. Finally, some simulation results with nonlinear loads are presented to verify the effectiveness of the proposed inverters
