Closed-Loop Switched Capacitor Cuk Converter Topology for Voltage Regulation and PFC Applications

Converters of AC-DC nature are pivotal to supplying power in electronics, charging equipment, and renewable energy integration. A closed-loop Cuk converter with switched capacitor network and PID controller was proposed in this paper to mitigate the limitations of open circuit Cuk converter topology to ensure improved power factor from input along with low distortion in output, making it ideal for green energy and electric vehicle applications. Significant improvement in output voltage regulation and input power factor correction was found in the proposed closed-loop switched capacitor topology.
