Power supply topology, motor drive controller, and vehicle

A vehicle, comprising a power battery, a motor, and a motor drive controller, wherein the motor drive controller is configured to convert a direct current output by the power battery into an alternating current, and the alternating current is used to drive the motor;

• or
• the motor drive controller is configured to convert an alternating current output by the motor into a direct current, and the direct current is used to charge the power battery,
• wherein the motor drive controller comprises a drive circuit, a control circuit, and a power supply topology,
• wherein the power supply topology is configured to supply power to the drive circuit and the control circuit, and the power supply topology comprises:
• a first flyback power supply coupled to a first battery module, the first flyback power supply configured to convert a first direct current output by the first battery module into a second direct current, wherein the second direct current is used to supply power to a lower bridge arm drive circuit in the motor drive controller;
• and
• a first forward power supply coupled to the first flyback power supply, the first forward power supply configured to convert the second direct current into a third direct current, wherein the third direct current is used to supply power to an upper bridge arm drive circuit.
