Auxiliary Power Network Architecture for 10 kV SiC-Based Power Electronics Building Blocks
2020
This paper proposes a two-stage auxiliary power network architecture for 10 kV SiC-based power electronics building blocks after comparing advantages and disadvantages of different auxiliary power supplies. Standalone introduction of the wireless power transfer converter and the current-transformer based gate-driver power supply serving as the first-and second-stage are given. Combination test results of the two-stage system is shown including normal operation, fault response, and operation in the high voltage, high dv/dt system.
