▼a Solid state transformer (SST) is considered an emerging and disruptive power electronics technology for medium voltage (MV) (2 kV-35 kV) applications including smart distribution system, traction transformer, ship power and renewable energy. SST |

▼a Three-stage SST with ac-dc-dc-ac scheme is the most widely studied and adopted approach since it can achieve most of the smart features and owns best control flexibility. However, the major disadvantage of this scheme is reduced efficiency due t |

▼a A novel current fed series resonant converter (CFSRC) is proposed for the first time that can address many technical challenges in DACX applications. (1) It helps MV MOSFETs achieve ZVS operation under wide input voltage and load range. Thus, hi |

▼a The 15 kV SiC MOSFETs developed by Wolfspeed enable simple and robust two-level DACX where the peak voltage stress is less than 12 kV. Chapter 3 revisited the characterizations of 15 kV SiC MOSFETs including switching loss, Ron, thermal, output |

▼a Resonant capacitors are distributed on both sides of the transformer to minimize number of MV MF SiC MOSFETs. Inherent cycle by cycle current-limit capability is achieved by paralleling diodes on low voltage (LV) resonant capacitors. The theoret |
