摘要: This paper presents one cycle control of bridgeless single-phase ac-dc power factor correction (PFC) rectifier based on Cuk topology. The topology does not possess input diode bridge and have only two semiconductor switches in the current flowing path during each interval switching cycle, which results less conduction losses better thermal management. is designed to work discontinuous mode (DCM). advantages converter also available when circuit introduced. One-cycle takes advantage pulsed nonlinear nature converters achieves instantaneous dynamic average value a switched variable. technique can provide correction, fast response, good source disturbance rejection, corrects error automatically.
