Second Order Sliding Mode Controller for a Bridgeless Boost Power Factor Correction

چکیده مقاله

In this paper, a sliding mode controller is applied to a Bridgeless Boost PFC converter. This controller is replaced with the traditional PI controller to improve the dynamic performance, stability, and attenuate the output voltage ripple. Moreover, by using a bridgeless converter, lower power dissipation can be achieved from the elimination of the diode bridge. The simulation results in SIMULINK MATLAB show the performance of the sliding mode controller in a bridgeless boost PFC converter with fast dynamic response, low under- shoot and stability of the controller.
