“…The use of the Ćuk converter as a PFC is mainly due to its interesting structure, which includes constant current sources at the input and output, eliminating the need for an input filter and naturally limiting the inrush current. These features make the topology suitable for single-stage AC-DC battery chargers [31], [32] and LED lamp drivers [33]. To aid in the understanding of the study, the conventional Ćuk rectifier's structure is presented in Figure 1.…”

This paper provides a comprehensive analysis, including static, dynamic, and experimental validation, of a voltage-doubler Ćuk rectifier operating in the discontinuous conduction mode (DCM) for singlephase applications. The proposed topology integrates two classic Ćuk rectifiers through a three-position switch, allowing for either a doubled output voltage or reduced voltage efforts compared to the conventional topology. The voltage gain is increased while maintaining the step-up/step-down characteristic of the Ćuk family and power components are activated only in a half-cycle of the electrical grid, thus reducing the current efforts in the semiconductors. These features make the Ćuk converter suitable for higher voltage applications. The proposed topology is analyzed in DCM, where a high power factor is naturally achieved without a current control loop. An experimental prototype of 1 kW is built to verify the theoretical analysis, and the results show an efficiency of 94.68% with an input current THD of 1.86% ate rated power, including an output voltage control loop. Furthermore, the proposed topology is compared to the conventional Ćuk rectifier, both operating in DCM and with power factor correction (PFC).
