Constant-frequency reduced-state sliding mode current controller for Cuk converters

摘要

A constant-frequency reduced-state sliding mode current controller for Cuk converters requiring a fast dynamical response over a wide range of operating conditions is proposed. The various issues concerning the theoretical derivation and implementation of the proposed controller are discussed. Preliminary verification and evaluation of these controllers are performed through simulation and experiment. It is illustrated that commendable control performances can be achieved with the proposed controller.
