Simplified power conversion systems for vehicles

A method of controlling a power conversion system of a vehicle, the power conversion system comprising:

• 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;
• a second switch;
• and
• a system control electronic control unit communicatively coupled to the first switch and the second switch,
• the method comprising:
• determining, by the system control electronic control unit, whether the vehicle is in a grid-connected mode or a stand-alone mode;
• in response to the vehicle being in the grid-connected mode:
• operating the first switch to connect the power conditioning device of the power conversion system with the boost converter of the power conversion system;
• and
• operating the second switch to connect the inverter of the power conversion system with the transformer of the power conversion system;
• and
• in response to the vehicle being in the stand-alone mode:
• operating the first switch to connect the battery of the power conversion system with the boost converter;
• and
• operating the second switch to connect the inverter with the electric motor of the power conversion system.

A vehicle including a power conversion system, the power conversion system comprising:

• 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, wherein
• 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.
