Interleaved series input parallel output zero-voltage-switching converter

This paper presents a series input parallel output interleaved converter, which utilizes two forward converters connect in series input to share the input voltage, and parallel output to share the output current. The Zero-Voltage-Switching (ZVS) of main switches can be achieved through the resonant between the leakage inductance of transformers and the active clamp capacitance. Two current double rectifiers are connected in parallel at the low-voltage side to reduce the output current ripple and share the output current. All these advantages make the converter with low output voltage, high output current with low current ripple, and low voltage stress across all switches. Finally, the detail operation principle and simulations results are provided.
