A sliding mode controller for the current-source parallel-resonant converter with zero-voltage switching

This paper presents a new switch control strategy for the current-source parallel-resonant converter, which provides zero-voltage switching conditions. To implement the new control technique, a sliding mode controller is proposed. The controller design is carried out using an averaged large-signal model of the converter, and allows determination of the main constraints of the controller parameters. The controller provides fast transient response, absence of steady-state errors in the output voltage and a robust output voltage response in relation to the input voltage and load disturbances
