An improved lossless passive snubber cell for PFC boost converter
2013 3rd International Conference on Electric Power and Energy Conversion Systems, 2013An improved lossless passive snubber cell for power factor correction (PFC) boost converter is proposed. All of the semiconductor devices in the boost converter are operated under soft switching condition. The switch operates at zero current switching (ZCS) turn on and zero voltage switching (ZVS) turn off.

A novel passive lossless soft-switching snubber for PWM inverters
2009 Chinese Control and Decision Conference, 2009This paper presents a novel passive lossless snubber circuit for pulse-width modulation (PWM) inverters to achieve soft-switching purposes without an extra switch and additional control circuitry. This novel passive lossless soft-switching snubber employs an inductor/capacitor snubber circuit for each switching device in an inverter to achieve passive ...

A boost converter with lossless snubber under minimum voltage stress
APEC. Seventeenth Annual IEEE Applied Power Electronics Conference and Exposition (Cat. No.02CH37335), 2003A passive lossless turn-on/turn-off snubber network is proposed for the boost PWM converter. Besides the benefit of small number of added components, all the devices block the voltage no more than the output DC voltage. The operation principle and design guideline is presented.

Passive lossless snubber for CCM PFC based on magnetic coupling
2011 International Conference on Electrical Machines and Systems, 2011Boost converter is the most popular topology in power factor corrector (PFC), which contains a switch and a diode. However the reverse recovery characteristic of silicon material diode enlarges the turning-on power losses of switch. In this paper, a novel passive lossless snubber based on magnetic coupling is proposed for continuous conduction mode ...

A novel passive lossless snubber for high power multilevel inverters
APEC. Seventeenth Annual IEEE Applied Power Electronics Conference and Exposition (Cat. No.02CH37335), 2003A novel passive lossless snubber circuit for multilevel inverters is proposed in the paper. The topology of it is simple and requires no extra control. In order to reduce the high voltage stress on power switches of multilevel inverters with the proposed snubber circuit, an improved snubber circuit is presented by adding separate low-power DC sources ...

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 ...

Active-Clamp Forward Converter With Lossless-Snubber on Secondary-Side
IEEE Transactions on Power Electronics, 2019This paper proposes a novel active-clamp forward converter (ACFC) with a lossless-snubber on the secondary-side, which combines a resonant capacitor and a clamping diode with an output inductor in parallel. The conventional ACFC achieves zero-voltage-switching on switches of the primary-side during dead time for reducing the switching loss and voltage ...

A lossless snubber for DC/DC converters and its application in PFC
Proceedings IPEMC 2000. Third International Power Electronics and Motion Control Conference (IEEE Cat. No.00EX435), 2002A passive lossless snubber is proposed in this paper to reduce switching losses and EMI noise by restricting di/dt and dv/dt of the switching device. As an example, a boost convertor with the lossless snubber is presented to illustrate the operation principle and theoretical analysis in details.
