A power supply topology, a motor drive controller, and a vehicle are provided. The power supply topology includes a first flyback power supply (201) and a first forward power supply (202). The first flyback power supply (201) is coupled to a first battery module, and is configured to convert a first direct current output by the first battery module into a second direct current, where the second direct current is used to supply power to a lower bridge arm drive circuit in the motor drive controller. The first forward power supply (202) is coupled to the first flyback power supply (201), and is configured to convert the second direct current into a third direct current, where the third direct current is used to supply power to an upper bridge arm drive circuit. The power supply topology is configured to supply power to the motor drive controller, thereby reducing a size of a transformer, and saving space of the whole vehicle.
