High-low voltage isolated pulse lamp control circuit, pulse lamp and refrigerator

The utility model relates to the technical field of electronic circuits, and provides a high-low voltage isolated pulse lamp control circuit, a pulse lamp and a refrigerator, the high-low voltage isolated pulse lamp control circuit comprises a trigger sub-circuit, a thyristor and a step-up transformer, the anode of the secondary coil of the step-up transformer is connected to the high-voltage trigger stage of the pulse lamp; the isolation controller outputs a signal to the control end of the thyristor according to the signal input to the trigger sub-circuit so as to control the state of the thyristor; when the thyristor is in a conducting state, the voltage of the primary coil of the boosting transformer is 0; when the thyristor is in a cut-off state, the primary coil of the boosting transformer has a first voltage, so that the secondary coil outputs a second voltage to the high-voltage trigger stage. According to the pulse lamp control circuit, the input of the isolation controller is controlled to control t
