The invention belongs to the technical field of power supply charging, and discloses a silicon carbide power supply charging control system and method, a medium, equipment and application. The siliconcarbide power supply charging control system comprises a three-phase rectification circuit, a single-path full-bridge LLC circuit and a full-bridge rectification circuit, and the three-phase rectification circuit is electrically connected with the single-path full-bridge LLC circuit and the full-bridge rectification circuit in sequence; initial three-phase alternating-current voltage passes through the three-phase rectification circuit, the single-path full-bridge LLC circuit and the full-bridge rectification circuit in sequence, and then target output voltage is obtained. By using the silicon carbide power supply charging system provided by the invention, after 380V three-phase alternating current voltage is input into the silicon carbide power supply charging system, the purposes that the output voltage is 1100V, the output current is 40A and the efficiency is improved by 3-5% compared with the traditional SIC charging power supply using a silicon device are achieved, the switchingspeed is high, the conduction loss is small, the size of the designed product is smaller, and thus, the battery cost is greatly reduced.
