  • SOLID STATE TRANSFORMER CONTROLLER
    Publication number: 20230402936
    Abstract: Disclosed herein is a system for controlling a solid state transformer (SST), the SST comprising an AC-to-DC stage, a DC-to-AC stage, and a DC-to-DC stage coupled between the AC-to-DC stage and the DC-to-AC stage, the DC-to-DC stage comprising one or more DC-to-DC converters. The system comprises a stored energy controller coupled to the AC-to-DC stage, the energy controller configured to control the total amount of stored energy within the capacitors of the SST; a power flow controller coupled to the DC-to-AC stage, the power flow controller configured to control power flow in the SST; and one or more energy balancing controllers each coupled to a corresponding DC-to-DC converter, each energy balancing controller configured to balance energy in the corresponding DC-to-DC converter. In some embodiments, the stored energy controller, the power flow controller and the one or more energy balancing controllers are decoupled from one another.
