An improved passive lossless turn-on and turn-off snubber
Proceedings Eighth Annual Applied Power Electronics Conference and Exposition,, 2002An improved passive lossless turn on/off snubber is proposed, where energy trapped in the snubber is transferred to both the DC rail and the load. A wider operational range of load current, a higher switching frequency and lower peak switch current make this circuit more practical than conventional lossless snubbers. Design equations, simulations based

Optimal Design of Lossless Passive Snubber for DC/DC Converters
First International Conference on Innovative Computing, Information and Control - Volume I (ICICIC'06), 2006This paper presents an optimal design of lossless passive snubber for DC/DC converters, which offers an efficient and best design method. The proposed method can not only reduce the spike voltage Vdsp of a power switch in the circuit, but also raise the conversion efficiency of the converter.

A novel lossless passive snubber for soft-switching boost-type converters
IEEE Transactions on Power Electronics, 1999A novel lossless passive snubber is proposed for soft switching boost-type converters. The proposed snubber does not use any auxiliary switches, but uses two identical snubber capacitors which are charged in parallel at turn off of the main switch and discharged in series at turn on automatically, and the discharged energy is recovered effectively ...

A passive lossless snubber cell for nonisolated PWM DC/DC converters
IEEE Transactions on Industrial Electronics, 1998A passive lossless snubber cell is proposed to improve the turn-on and turnoff transients of the MOSFETs in nonisolated pulsewidth modulated (PWM) DC/DC converters. Switching losses and EMI noise are reduced by restricting di/dt of the reverse-recovery current and dv/dt of the drain-source voltage.

Battery discharger applications of high frequency boost converter with lossless snubber
2002 IEEE 33rd Annual IEEE Power Electronics Specialists Conference. Proceedings (Cat. No.02CH37289), 2003In this paper, a power converter with an auxiliary circuit, which has no snubber loss, has been suggested to reduce the diode reverse recovery loss. The small saturable inductor is added to reduce the reverse recovery loss of the diode. Due to the addition of a saturable inductor, much resonant energy is reduced.

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 passive lossless snubber cell with minimum stress and wide soft-switching range
2009 IEEE Energy Conversion Congress and Exposition, 2009A passive lossless snubber cell and its dual structure for reducing the switching loss of a range of switching converters are presented. The proposed snubber cell has several advantages over existing snubbering techniques. First, it provides zero-current-switching (ZCS) and zero-voltage-switching (ZVS) conditions for turning on and off, respectively ...
