An electrical system includes an alternating current (AC) source; a transformer rectifier unit (TRU) connected to the AC source, the TRU configured to receive AC power from the AC source, convert the AC power to direct current (DC) power, and output DC power; a DC bus configured to receive the DC power output by the TRU; at least one DC load powered by the DC bus; and a shunt regulator connected to the output of the TRU, the shunt regulator configured to overload the output of the TRU in the event of an overvoltage condition at the output of the TRU, such that a voltage available to the DC bus during the overvoltage condition does not exceed a reference voltage. |
