Abstract
A holdup energy arrangement can include a motor control module configured to connect to motor power electronics to operate an inverter to control a motor. The motor control module can operate at a lower voltage than the motor power electronics. The arrangement can include a power supply operatively connected to the motor control module and configured to provide power the motor control module and a converter operatively connected to the power supply and configured to be electrically connected to a DC link capacitor of the motor power electronics. The arrangement can also include a logic control module configured to control the converter to selectively allow energy to flow from the DC link capacitor, through the converter, and to the power supply to provide holdup energy to the power supply with energy from the DC link capacitor.
