Abstract
An energy conversion device is provided. The device includes: a reversible pulse width modulation (PWM) rectifier (11) and a motor coil (12), where the motor coil (12) includes at least a first winding unit and a second winding unit, and the first winding unit and the second winding unit are both connected with the reversible PWM rectifier (11). The first winding unit is connected with at least one of neutral lines in the second winding unit, where at least one neutral line of at least one of the winding units is connected with a first end of a first direct current (DC) charging and discharging port (3), the reversible PWM rectifier (11) is connected with a first end of a external battery (2) and a second end of the external battery (2) respectively, and a second end of the first DC charging and discharging port (3) is connected with the second end of the external battery (2).
