Hybrid ZVS Converter with a Wide ZVS Range and a Low Circulating Current [PDF]
Journal of Power Electronics, 2015 This paper presents a new hybrid soft switching dc-dc converter with a low circulating current and high circuit efficiency. The proposed hybrid converter includes two sub-converters sharing two power switches. One is a three-level PWM converter and the other is a LLC converter.
