“…In the circuit schematic of Cúk converter shown in Fig. 1, inductors L 1 and L 2 are assumed sufficiently large so that the converter will not enter DICM or DQRM [5]. For operating in DCVM, it is also assumed that the capacitor is sufficiently small so that it is fully discharged in a fraction of the switching cycle.…”

The Cúk converter operating in discontinuous capacitor voltage mode (DCVM) inherently benefits from PFC features as unity power factor can be achieved by using a constant duty cycle and switching frequency. In this paper, the switch network modeling technique is applied to the Cúk converter operating in DCVM in order to develop its smallsignal model under the assumption that it is fed by a dc voltage source. Afterwards, the model is extended to derive the smallsignal behavior of the converter while operating as a PFC converter. The validity of the proposed model is confirmed by both simulation and experimental results.

“…One of the classic converters used for this application is the Cúk converter. Compared to buck-based and boost-based structures, the Cúk converter has several advantages such as continuous and low ripple input and output currents and wide range of output voltage [4,5].…”

“…To satisfy the forthcoming harmonic standards, such as IEC 1000-3-2, PFC's serving as front-end converters have been attracting more and more attention. Among various PFC topologies, the Cúk PFC is deemed desirable for its continuous input and output currents, ripple-free input current, small output filter, and wide output voltage range [9]- [10]. However, the switch utilization factor of the Cúk topology is much lower than other topologies, such as the buck topology and the boost topology [11].…”

A novel zero-voltage-transition (ZVT) pulsewidth modulated (PWM) Cúk power-factor corrector (PFC) is proposed to achieve unity power factor under zero-voltage-switching (ZVS) operations. In the proposed ZVT PWM Cúk PFC, not only the power switch, but also the power diode, commutate under ZVS. The proposed topology has the shortest ZVT time and, thus, the shortest minimum duty cycle compared with other ZVT PWM topologies. The resonant inductor can be discharged regardless of the state of the main switch. Extremely short ZVT time and robust discharge of the resonant inductor make the proposed topology well qualified for variable-duty and highswitching-frequency applications. Analytical studies, design rules, and experimental waveforms of the ZVT PWM Cúk PFC are presented in detail.
