Electric drive system, control method and related equipment

A control method used to control an electric drive system, comprising:

• controlling a first switch to be turned off, an upper bridge arm of a second inverter to be turned on, and a lower bridge arm of the second inverter to be turned off, and a lower bridge arm and an upper bridge arm of a corresponding phase of a first inverter to be alternately turned on through synchronous or asynchronous first PWM signals of each phase in response to connecting a first direct current power supply apparatus whose output voltage is lower than a voltage of a battery to a distal side of the second inverter, such that the electric drive system enters a boost charging mode in which the first direct current power supply apparatus first charges a winding of the corresponding phase of an open winding motor, and then charges the battery through the winding of the corresponding phase of the open winding motor.

A non-transitory computer-readable storage medium storing a program, wherein when the program is executed by a processor, the processor performs the control method according to 13.

A control apparatus, comprising:

• a boost charging controller configured to:
• control a first switch to be turned off, an upper bridge arm of a second inverter to be turned on, and a lower bridge arm of the second inverter to be turned off, and a lower bridge arm and an upper bridge arm of a corresponding phase of a first inverter to be alternately turned on through synchronous or asynchronous first PWM signals of each phase in response to connecting a first direct current power supply apparatus whose output voltage is lower than a voltage of a battery to a distal side of the second inverter, such that the electric drive system enters a boost charging mode in which the first direct current power supply apparatus first charges the winding of the corresponding phase of an open winding motor, and then charges the battery through the winding of the corresponding phase of the open winding motor.
