The invention belongs to the technical field of charging power supplies, and discloses a short-circuit control method and system for a silicon carbide charging power supply, a medium and an application. The short-circuit control method for the silicon carbide charging power supply comprises the steps of obtaining a current charging voltage value collected by a charging detection module; determining a target level matched with the current charging voltage value; and controlling a silicon controlled rectifier module to execute corresponding target processing according to the target level. According to the invention, the target level matched with the current charging voltage value is determined according to the current charging voltage value acquired by the charging detection module in real time, so that the silicon controlled rectifier module is controlled to be switched on or off according to the target level; the silicon carbide module is disconnected or closed to achieve the purpose of power failure when abnormality is detected quickly and effectively, the purpose of dozens of times higher than the turn-off speed of a mechanical short-circuiter is achieved, the switching speed ishigh, the conduction loss is small, the abnormality judgment speed of the charging power supply is greatly increased, and the service life of the charging power supply is greatly prolonged.
