Abstract
A system and method for preventing over voltages in a power system coupled to an electric machine are disclosed. Briefly described, one embodiment is a method comprising detecting an operating voltage on a high voltage direct current (HVDC) bus, determining if at least one component of the power system is operational, communicating a signal to a power converter of the power system when the detected operating voltage is greater than a threshold voltage and when the component is not operational, and shorting together a plurality of terminals of the electric machine.
