One of the main disadvantages of the multi-level solid-state transformer (SST) system is the voltage imbalance on the output of the rectifier modules. This voltage imbalance can be caused by parameter mismatch of the active and passive components, di

A modular multi-level converter (MMC) is composed of many sub-modules (SMs). Each SM needs a power supply to drive insulated-gate bipolar transistor (IGBT) and control power. The MMC system has a power of 100MW, a dc link voltage of 250kV, and a tota
