Abstract
Power Factor Correction (PFC) converters are essential in designing any charging architecture, regardless of the battery's capacity and the application. Nevertheless, power converters, having continuous output current features, are widely used for battery charging applications. In contrast, converters with continuous input current characteristics exhibit better PFC performance. The Cuk converter can be an ideal PFC charger due to its continuous input and output current features. This article presents a hybrid Cuk converter with a switched capacitor configuration as a 48 V - 12 Ah battery charger. The switched capacitor allows the converter to operate at nearly 50% duty cycle. Along with the typical average current mode (ACM) control, an... (More)

The switched capacitor allows the converter to operate at nearly 50% duty cycle. Along with the typical average current mode (ACM) control, an additional voltage compensator has also been proposed to ensure the typical constant-current and constant-voltage (CC-CV) mechanism. Overall, the topology improves the power quality significantly with a unity power factor and only 2.32% THD. (Less)
