  • Electrical architecture for powering multiple transport refrigeration units
    Patent number: 11976862
    Abstract: A multi-unit transport refrigeration system including: a first transportation refrigeration unit configured to refrigerate a first transport container; a second transportation refrigeration unit configured to refrigerate a second transport container; and an energy management system including: an energy storage device configured to store electricity to power the first second transportation refrigeration unit; and a power conversion system electrically connecting the energy storage device to the first transportation refrigeration unit and the second transportation refrigeration unit, the power conversion system including: a first DC/DC converter configured to increase a voltage of the electricity received from the energy storage device from a first voltage to a second voltage; and a first DC/AC inverter configured to convert the electricity received from the first DC/DC converter from DC to AC and then convey the electricity to at least one of the first transportation refrigeration unit or the second transporta
