Abstract
This application provides a power supply system for a motor control module and a vehicle. The power supply system includes a first current limiting unit and an isolation unit. An output end of a first direct current power supply is coupled to a first input end of the isolation unit to form a first power supply loop with the isolation unit. A first output end of a second direct current power supply is coupled to one end of the first current limiting unit. Another end of the first current limiting unit is coupled to a second input end of the isolation unit to form a second power supply loop with the isolation unit. The second power supply loop is connected in parallel to the first power supply loop.
