  "textContent": "This application provides a motor drive system, a power system, and an electric vehicle, and relates to the field of power electronic technologies. The drive system is configured to drive a motor that uses a power battery pack as a power supply. The power battery pack includes at least two battery modules that are independent of each other, the drive system includes at least two direct current-alternating current DC-AC circuits, and the battery modules one-to-one correspond to the DC-AC circuits. Each battery module is correspondingly connected to an input end of one DC-AC circuit, and an output end of each DC-AC circuit is connected to a corresponding winding of the motor. The DC-AC circuit is configured to convert a direct current provided by the corresponding battery module into an alternating current to drive the corresponding winding of the motor.",
