Abstract
A power conversion system for a vehicle includes a power conditioning device, a boost converter, an inverter coupled to the boost converter, a transformer, a second rectifier coupled to the transformer, an electric motor, a battery coupled to the second rectifier, a first switch configured to selectively connect the boost converter with the power conditioning device or the battery, and a second switch configured to selectively connect the inverter with the transformer or the electric motor. The first switch connects the power conditioning device with the boost converter and the second switch connects the inverter with the transformer in response to the vehicle being in a grid-connected mode, and the first switch connects the battery with the boost converter and the second switch connects the inverter with the electric motor in response to the vehicle being in a stand-alone mode.
