Indirect Voltage Control of a Stand-Alone Inverter

Abstract

This paper discusses the control of the output voltage of a stand-alone single-phase inverter by directly controlling the output filter capacitor current. Compared to the conventional voltage control scheme, the proposed control approach has the potential of achieving higher bandwidth and hence improved total harmonic distortion (THD) of the output voltage. The proposed method depends on the value of the output filter capacitance. A method to estimate the output filter capacitor based on a rms control loop is also presented. Simulation and experimental results presented validate the proposed scheme.
