technical field [0001] The invention relates to a power supply circuit, specifically, a superimposed boosting power supply system for an electrostatic dust collection device based on an inductance filter circuit. Background technique [0002] The high-voltage electrostatic dust collection device is an air purifier that can not only ensure the air volume but also absorb fine particles. High-voltage electric dust collection is to apply high voltage to the two electrodes of the permanently charged filter element. When the two electrodes are discharged, the passing dust is charged, so that the dust in the air is adsorbed to the specially processed, permanent filter under the action of electricity. on the live filter. When the high-voltage electrostatic precipitator is working, it needs a boost power circuit to provide it with a working voltage, and the effect of the air purifier on the high-voltage electrostatic precipitator on the dust in the air depends on whether the high vo...
