Soft-switching vector control for resonant snubber based inverters [PDF]
, 1997 This paper gives a new classification of soft-switching inverters according to the principle of operation. After discussing the soft-switching phenomena in hard-switching inverters, the concept of soft-switching vector (SSV) is introduced.

Analysis and evaluation of a lossless turn-on snubber [PDF]
Proceedings of APEC 97 - Applied Power Electronics Conference, 2002 A lossless turn-on snubber was studied analytically, by simulation and experimentally. Limits were found for the proper operation of the snubber and are expressed as permissible duty cycle as a function of input current. It was found that a modified version of the snubber, which includes a tapped main inductor, improves the performance by allowing a ...

A single phase voltage regulator module (VRM) with stepping inductance for fast transient response [PDF]
, 2007 A single-phase fast transient converter topology with stepping inductance is proposed. The stepping inductance method is implemented by replacing the conventional inductor in a buck converter by two inductors connecting in series.

Passive lossless snubber for double‐ended flyback converter
IET Power Electronics, 2015 Double‐ended flyback converter is one of the most popular topologies employed as a power supply or a power factor correction converter. Reducing switching losses at high switching frequencies is essential. In this study, a passive lossless snubber for double‐ended flyback converter is introduced.

A novel soft-switching inverter using resonant inductor freewheeling [PDF]
, 1997 A novel topology of the voltage-source soft-switching inverter for induction motor drives is presented. The key of this topology is to employ two fractional-duty auxiliary switches and one resonant inductor per phase to provide a favorable zero-voltage ...

High-Efficiency NPC Multilevel Converter Using Super-Junction MOSFETs [PDF]
, 2016 Super-junction MOSFETs exhibit low on-state resistances and low switching losses. However, the reverse recovery behavior of their intrinsic diodes and their output capacitance characteristics make their deployment in freewheeling locations challenging ...

High Frequency Transformer Based Improved Gamma ZSI with Lossless Snubber
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018 This paper presents an improved single phase high frequency isolated gamma Z-source inverter (ZSI) with clamped diode. It consists of a high frequency transformer between the inverter bridge and load. A lossless snubber diode is employed to provide voltage clamping across the DC-link voltage to overcome the voltage overshoots caused by the leakage and ...
