摘要：
Existing DC-DC converter has some shortcomings, such as low power, low efficiency, and poor load adaptability. For which a novel soft switching three-level DC-DC converter is proposed, a step-down winding in secondary side of high-frequency transformer in series with commutation inductance is added to ensure the devices soft switching in the full power scope using asymmetrical phase-shift PWM control. The operation process and characteristics of the circuit are analyzed, and a prototype is completed. Experimental results verify the proposed DC-DC converter with high input voltage, wide ZVS range, and high efficiency.
