【 摘 要 】
This paper presents the PWM control strategies for three-switch isolated boost DC-DC converter. By inserting the extra states into the conduction time of switches, the current input is still continuous; unchanged primary and secondary voltage waveforms of the high-frequency (HF) transformer. The parameter design guideline with the different PWM control strategies is discussed. A 400 W prototype has been tested in the laboratory to verify the performance of the three-switch DC-DC converter with two PWM control strategies and a PI controller was used to clarify the DC output voltage at 400 V. The simulation and experimental results are shown to validate the theoretical analysis.
