A single stage single switch power factor correction converter

The flyback-flyback single stage converter operated in DCM+DCM is easy to control bus voltage, but it hard to control stress of switch. We propose a new converter having low voltage stress on its switch. The flyback converter is simplified into buck-boost form. Then the PFC flyback transformer is replaced by an inductor The switch of both PFC and DC/DC stages are merged, and a diode is used to ...

Soft-Switching Single-Stage Power Factor Correction Converter

1 This work is supported by NASA-STTR grant # NAS10-00005 AbstractA single-stage, ZVT-PWM, power factor correction converter is proposed in this paper. Zero-voltage switching for the main switch and zero-current switching for the auxiliary switch are realized by utilizing the leakage inductance of the output transformer and the capacitance of the switches. As a result, no additional resonant co...

A Novel Single-stage AC/DC Converter with ZVS Characteristic

A novel single-stage AC/DC converter is proposed in this letter. The converter is designed by integrating a sepic circuit and a flyback circuit, the circuit work in the quasi-resonance state, and the switch is turned on in the zero voltage switching (ZVS) state, which decreased the switching losses of the converter Streszczenie. Opisano nowy konwerter AC/DC. Układ pracuje w stanie quasi-rezonan...

Single Stage Techniques for Power Factor Correction

Medium and high power switch mode power supplies SMPS (>500W) used in telecommunications stations are normally based on the full-bridge DC-DC converter with isolation transformer. According to the transistors states, the full-bridge converter allows four different switching sates which can be used to control the output voltage of the SMPS, and to perform the power factor corrector (PFC) functio...

A Design of Boost Derived Three Level Isolated Single-Stage Power Factor Correction Converter

For low-cost isolated ac/dc power converters adopting high-voltage dc-link, research efforts focus on single-stage multilevel topologies. This paper proposes the design of boost derived three level isolated single-stage PFC converter. The proposed topology significantly reduces the switching losses and zero current switching with zero voltage switching. This topology achieved through an effecti...
