摘要：

This paper presents an optimized high-frequency transformer design for a 6 kV, 100 kW Isolated Modular Multilevel DC-DC (iM2DC) converter for shipboard application with 50 kHz transformer ac frequency. The Phase Shifted Square Wave Modulation (PS-SWM) scheme produces an unconventional, non-sinusoidal ac voltage waveform that makes the high-frequency transformer design challenging. This paper proposes an optimized transformer design method by accurately estimating the transformer's power loss for iM2DC converter while still utilizing the advantages associated with PS-SWM modulation. The findings are later validated by a down scaled prototype.
