description The utility model relates to a switch power supply used for electromagnetic induction heating equipment. The switch power supply comprises a high-voltage direct-current source filter circuit (1), a switch power supply output filter circuit (3) and a low-voltage power supply conversion circuit (4). The switch power supply is characterized in that the switch power supply also comprises a BUCK circuit (2); an output terminal of the high-voltage direct-current source filter circuit (1) is connected with an input terminal of the BUCK circuit (2); the output terminal of the BUCK circuit (2) is connected with the input terminal of the switch power supply output filter circuit (3); the output terminal of the switch power supply output filter circuit (3) is connected with the input terminal of the low-voltage power supply conversion circuit (4). According to the switch power supply of the utility model, the BUCK circuit is used to realize a voltage reduction function; a voltage impact to a high-voltage MOSFET is small
