| Abstract: | In order to decrease great consumption during switching process caused by the hard-switching in a uninter-ruptible power supply(UPS) discharge system,a novel passive lossless soft-switching(PPSS) topology based on Buck-Boost converter is proposed.Consumed energy on IGBT is transferred and fed back to load by using snubber circuit with inductance,capacitance and diode.Firstly,the controlling thoughts and different operation modes are introduced.Secondly,stress of the switch elements is analyzed and the param... |
