Abstract

Boost inverter is able to generate an AC voltage whose peak value can be larger or smaller than the DC input voltage in a single stage. The boost inverter consists of two individual boost DC-DC converters. Each of the boost DC-DC converters has to be controlled in variable operating point condition. This paper proposes two voltage mode controllers. First one is conventional feedback controller based on small signal model. Second one is a simplified voltage mode controller based on feedforward pulse width modulation (FF-PWM) and simple voltage feedback loop to control the output voltage of the boost inverter. The second controller gave better result. The controller also ensures output voltage to meet IEEE Std 519 voltage harmonic limits. Unlike most previously proposed controllers, the proposed method is based only on output voltage feedback, making unnecessary the inductor current measurement. The control method is verified by means of simulations.
