| Abstract |
A regenerative snubber for three-level high-power GTO inverter having simple construction and high efficiency is proposed. It consists of series inductor and shunt capacitor snubbers with DC/DC converter for energy recovery trapped in the snubbers. In particular, the new DC/DC converter as an essential component of regenerative snubber has very low switching loss due to resonant operation with zero voltage switching and has small size due to high switching frequency over 10 KHz using power transistors. The proposed regenerative snubber is also thought to be applicable for other multi-level high power GTO inverters. |
