Family of Soft-Switching Single-Switch PWM Converters with Lossless Passive Snubber
IEEE Transactions on Industrial Electronics, 2014To increase the power conversion density, decrease switching losses and electromagnetic interference (EMI), and provide safe operating area for a switch, applying snubber circuits which provide soft-switching conditions is inevitable. Among different types of snubber circuits, passive snubbers, due to their simplicity and robustness, are preferred ...

An improved active-clamp ZVS forward converter with a lossless snubber
INTELEC 2009 - 31st International Telecommunications Energy Conference, 2009In this paper, an improved active-clamp forward converter with a lossless snubber composed of a tapped inductor, a snubber capacitor and two diodes is proposed. By adding the lossless snubber at the secondary side of the active clamp forward converter, better ZVS operation, higher efficiency and lower ripple noise of the output voltage are achieved ...

A New Passive Lossless Snubber
IEEE Transactions on Power Electronics, 2021Galvanically isolated photovoltaic (PV) microinverters based on single-stage flyback topology have advantages: simplicity, better reliability, and low cost. But isolated flyback topology comes with voltage stresses on semiconductor switches caused by transformer leakage inductance.

Flyback lossless passive snubber
2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015To increase power conversion density, it is inevitably necessary to increase switching frequency. However, doing so has detrimental effects, including reduced efficiency and increased EMI under hard-switching operation. To prevent the side effects of high switching frequencies, soft switching methods present advantages.

A Novel Lossless Snubber for Boost Converters
2006 IEEE International Symposium on Industrial Electronics, 2006Advanced transportation technologies, such as hybrid-electric vehicles, battery-electric vehicles, and fuel cell vehicles, rely on high-power DC/DC converters to interconnect and manage their power systems. Boost converters are especially useful in stepping-up the voltage from a battery or fuel cell to match the electric motor voltage range.

A novel lossless snubber circuit
Proceedings, Fourth Annual IEEE Applied Power Electronics Conference and Exposition, 2003A simple lossless snubber circuit for use with a switch mode power converter is presented. The circuit uses a capacitor connected between the primary and tertiary windings of a transformer in such a way as to relieve the stress from the power semiconductor switch at both turn-on and turn-off.

Interleaved Flyback Converter with a Lossless Snubber
International Review of Electrical Engineering (IREE), 2014In this paper, an interleaved flyback converter with a lossless snubber is presented. By freewheeling the energy stored in a snubber, the overall efficiency is improved. In addition, the proposed converter has small output current ripple due to its interleaving structure. Since the proposed converter operates in discontinuous-conduction mode (DCM), the

A passive lossless snubber for Bidirectional Buck/boost converter
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017A passive lossless snubber for soft-switching Bidirectional Buck/boost Converter (BBC) is proposed in this paper. Although the conventional lossless snubbers can effectively alleviate the switching losses during turn on and turn off transients, they can be applied to only the unidirectional converters, but not a bidirectional converter.
