Abstract

The embodiments of the present application provide a charging and distribution control system and a charging and distribution system. The charging and distribution system includes a power factor compensation module, a half-bridge LLC resonant conversion module, and a DC / DC conversion module. Three analog signal control units (a first control unit, a second control unit, and a third control unit) are used to control their respective corresponding circuits, and a digital signal control unit (a main control unit) controls the three analog signal control units. This can achieve precise control of the circuit without affecting the speed at which the control unit controls the circuit, and also saves costs. In addition, the U-shaped structure in this application can make the overall layout simpler, the wiring shorter, and the system have better electromagnetic compatibility performance.
