Abstract
A single-phase H-bridge transistorised converter intended for front-end (FE) power conversion at a high power-factor and a constant desired output voltage has been analysed. Based on the desired boost-mode operation of the converter, the average state-space model has been derived from the basic circuit equations. Equilibrium points of operation of the converter have been obtained from the state-space model. As the converter is intended for use as a voltage source for an inverter, the requirement of maintaining a constant DC voltage at its output becomes a necessary criterion. Two feedback schemes for controlling the output voltage in closed-loop have been designed. Their performances have been compared by simulation studies. Some experimental studies on the converter operating in open-loop have been made and results obtained in the boost-mode of operation.
