| Abstract: | The output ripple suppression methods of a soft switching combination DC DC converter, working in current controlled discrete pulse modulation mode, are proposed. The optimal control pulse sequence to minimize output ripple is firstly analysed. Then the relationship among the hysteresis width, switching frequency and the output voltage ripple is discussed. Finally the design principles to reduce output voltage ripple and simulation results are proposed. The conclusions are important for control circuit design of the soft switching combination DC DC converters and inverters. |
