A New Soft-Switching Forward DC-DC Converter Operating in Discontinuous Conduction Mode
, 2002 The paper presents a simple soft-switching forward DC-DC converter suitable for low power applications. A lossless passive turn-off snubber is employed to provide zero voltage turn off of the switch as well as transformer reset.

Novel passive lossless turn-on snubber for voltage source inverters
IEEE Transactions on Power Electronics, 1997 A novel passive lossless turn-on snubber with a soft-clamped turn-off snubber circuit for voltage source inverters is proposed. The energy trapped in the snubber is recovered into the DC supply and load without any active devices, associated control circuitry, or resistors.

Flyback lossless passive snubber
2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015 To 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 circuit
Proceedings, Fourth Annual IEEE Applied Power Electronics Conference and Exposition, 2003 A 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.

A Novel Lossless Snubber for Boost Converters
2006 IEEE International Symposium on Industrial Electronics, 2006 Advanced 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.

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 ...
