Abstract
A system may be provided to perform multiple power conversion operations. The system may include a transformer interconnected between a high voltage DC bus and a low voltage DC bus, and an AC load connected to the transformer through an AC power supply line. The system may be configured to simultaneously provide power from the low voltage DC bus to the high voltage DC bus and the AC load, through the transformer. Further, the system may also be configured to simultaneously provide power from the high voltage DC bus to the low voltage DC bus and the AC load, through the transformer. And, the system may be configured to simultaneously provide power from a shore power source to the AC load, and, to the low voltage DC bus and high voltage DC bus through the transformer.
