  • High and medium voltage power converters with switch modules parallel driving a single transformer primary
    Patent number: 12132406
    Abstract: A multilink power converter with reduced winding voltage is disclosed, as well as various applications. In the disclosed embodiments, multiple primary switch modules have their inputs connected in series while using a single transformer winding connected in parallel to the modules' outputs through voltage blocking capacitors. Medium voltage solid-state transformers are presented, including three-phase power converters. Also presented are embodiments utilizing common mode inductors to equalize the currents of the high voltage modules.
    Type: Grant
