easy to control soft switching three phase inverter
A novel Passive Assisted Soft Switching Converter is presented in the paper.Soft Switching of the switch can be achieved by using Passive Assisted Resonant network.It is very attractive for high power application where IGBT is predominantly used as the power switch.Its operation principle is analyzed through its application to the boost converter.The condition of soft switching and the design considerations are analyzed in detail.The novel soft switching cell can be also used in other basic dc-dc converter.A 5kW~20kHz prototype which uses IGBT (insulated gate bipolar transistor) is made.The effectiveness of the proposed converter is confirmed by the experimental results.
