一种用于高降压比辅助电源的可扩展自供电平衡电路

This article proposes a new auxiliary power supply solution for medium-voltage converters using a unidirectional-balancing-cell-based approach. The proposed approach reduces the number of active devices and required driving circuitry by half compared with existing voltage-balancing circuit designs. In addition, it significantly reduces the size of the resonant tank by decoupling the $LC$ resonant ...
