This paper presents a new DC/DC converter for high input voltage and high load current applications. In order to adopt low voltage rating power devices in high voltage applications, two split capacitors with four active switches are used in the primary side to reduce the voltage stress of power switches at Vin/2. Two flying capacitances are used in order to automatically balance two split capacitor...
This paper presents a parallel resonant converter for high input voltage applications. In order to reduce the voltage stress of active switches, two half-bridge converters are connected in series at high voltage side. Flying capacitor is adopted between two series half-bridge converters to automatically balance two input capacitor voltages. Pulse frequency modulation scheme is adopted to regulate...
This paper presents a parallel zero voltage switching (ZVS) dc-dc converter with series connected transformers. In order to increase output power, two transformers connected in series are used in the proposed converter. Two buck-type converters connected in parallel have the same switching devices. The primary windings of series connected transformers can achieve the balanced secondary winding currents...
