Recent developments in medium-voltage (MV) silicon and silicon carbide (SiC) power
semiconductor devices are challenging state-of-the-art converter and auxiliary power supply …

The auxiliary submodule power supply is a vital component of a modular multilevel
converter submodule or any multi-submodule converter. Considering the high isolation …

The medium-voltage dc (MVDC) system are intensely investigated by both industry and
academy. However, how to realize a lower power circuit directly fed by MVDC is an …

In order to deal with the challenges in establishing a high input voltage high step-down
auxiliary power supply (APS) for modular converters, a flyback converter utilizing series …

In this paper, a high frequency current-fed isolated auxiliary power supply (HFCF-APS) is
proposed for medium-voltage module stack converters. Unlike conventional anxiliary power …

A common way of implementing MV insulated gate and/or auxiliary power supplies for
