A regenerative-passive snubber (RPS) for pulse-width modulation (PWM) two-switch forward converter (TSFC) is presented. The RPS circuit is recycled the magnetic energy stored in the transformer leakage inductor and is achieved zero voltage switching turn off of power switches. Moreover, the RPS provides the resonant path formed by snubber capacitors and the snubber inductor to achieve zero current switching (ZCS) turn on of switches. In addition, the output diodes turn on/off under ZCS. The proposed RPS-PWM TSFC is analysed and experimental result for a 160 W, 300 kH prototype at the output voltage of 32 V are obtained to verify the theoretical analysis.

“…Researchers and engineers have made efforts to improve the performance of PFCs, primarily paying attention to high efficiency, high power density and total harmonic distortion (THD) [3,4,5,6,7,8] related to the power factor and EMI. The trend in PFC development is to apply fewer components while achieving better performance and satisfying the proposed requirements.…”

A PFC circuit for applications higher than 2 kW is generally configured by an interleaved structure, which reduces component stress and the ripple of inductor currents and output voltage. However, when implemented with GaN HEMT and controlled by a double sliding mode, a high-power totem pole PFC could achieve better performance without an interleaved structure.

“…Although bridge rectifiers and bulk capacitors are widely used as power filters for the AC/DC systems because of their simple implementation and low cost, they produce excessive harmonic distortion and high peak input current, which lead to bad effect on power quality of the AC power grid. Therefore, the AC/DC converter with a power factor correction (PFC) is required to meet the harmonic regulations and standards [1][2][3][4][5][6][7][8].…”

This study presents a zero-voltage-transition (ZVT) bridgeless power factor correction (PFC) rectifier, which uses an auxiliary circuit with a transformer to achieve soft-switching for the main power switches. With the auxiliary circuit, the main switches can be ZVT turned-on without any additional voltage or current stresses. In addition, the auxiliary switch is turned-off with zero-current switching. Therefore, the switching loss of all power switches is reduced, and the overall rectifier efficiency is improved. The circuit topology, operation analysis and the components selection of the proposed rectifier are described in detail. Finally, a laboratory prototype of 700 W is implemented and tested to verify the performance of the proposed PFC rectifier.
