Power supply network, electric vehicle, and power conversion device

A power supply network that is mounted on a vehicle and supplies power to a load from a plurality of power supply paths, the power supply network comprising:

• a first power supply path connected to a main-machine drive power supply of the vehicle through a power conversion device and connected to the load;
• and
• a second power supply path connected to a power source different from the main machine drive power supply, connected to the load, and connected to the first power supply path through a switch,
• wherein the switch is closed when the first power supply path and the second power supply path are normal, and is opened when the first power supply path or the second power supply path is abnormal, wherein the power conversion device includes:
• a first inverter connected to the main-machine drive power supply;
• a second inverter connected to the first power supply path;
• a motor having a first winding connected to the first inverter and a second winding connected to the second inverter;
• and
• the second inverter operates according to a second torque command for regenerative braking of the motor, and the first inverter operates according to a first torque command obtained by adding an amount corresponding to the second torque command to a predetermined torque.
