| Abstract: | The detailed analyses and optimized design procedures of a novel passive lossless soft switching method for PWM converters are presented in this paper. And a 900 W full load power boost converter with this lossless passive soft switching method is built, which realizes zero current turning-on and zero voltage turning-off, its better efficiency is also confirmed compared with conventional boost converters. |
