The present application provides an energy conversion system and a power system. The energy conversion system may include a motor, a control module, an AC/DC conversion module, a first switch, at least one filter inductor and at least one second switch, wherein one filter inductor The first connection terminal can be connected to the first connection terminal of the AC power source through a second switch. In the case of driving the motor and charging the battery module at the same time, the control module can control the first switch to be turned off, the second switches in the at least one second switch to be turned on or off, and the control module of the AC/DC conversion module. The bridge arm switches act, so as to achieve the purpose of driving the motor and charging the battery module based on the voltage provided by the AC power supply. In the present application, the first switch, each second switch and each bridge arm switch can be controlled to work together to achieve the purpose of simultaneously driving the motor and charging the battery module, thereby improving the energy conversion efficiency, low cost and strong applicability. |
