Abstract

In accordance with disclosed embodiments, a power conversion system and method are provided. The power conversion system comprises a main power source configured to deliver drive power to a load and an add-on power module. The add-on power module comprises an isolated DC/DC converter and a low voltage source coupled in series with a high voltage source. The add-on power module is coupled to the main power source and the load and configured to output boost power to the load. The power conversion system further comprises a controller coupled to the main power source and the add-on power module, wherein the controller is configured to: determine that the load requires power from the main power source, and if so, direct boost power from the add-on power module to the load; and direct drive power from the main power source to the load when boost power falls below a predetermined threshold.
