| Abstract |
This paper presents a zero current switching predictive control strategy for a direct resonant converter which is part of a high voltage power supply. A voltage compensator is used to reduce the output distortion. The direct resonant converter and the voltage compensator consist of a three to single phase matrix converter supplying a series resonant circuit and an H-bridge converter, respectively. Input current, resonant tank capacitor voltage and compensator capacitor voltage are controlled by the predictive approach which selects the optimal switching state to be applied at every zero crossing of the resonant tank current. Since the converter is commutated at the zero current instants, the resonant tank current is controlled via the tank capacitor voltage. Simulation results verify the performance of the system. |
