PERFORMANCES COMPARISION OF INTERLEAVED ACTIVE CLAMP ZVS FORWARD CONVERTER AND INTERLEAVED ZVS HALF-BRIDGE CONVERTER FOR MODULAR POWER PROCESSOR

The operation, efficiency, and reliability of two topologies are compared for a modular power proces­sor. To simplify the gate drive circuits, N-P MOSFETs coupled active clamp method is newly proposed. An efficien­cy above 89% for the 50-100% load range is achieved. This paper provides design details for the power stage and the current-mode control circuit of an interleaved active clamp ZVS forward converter.
