Energy-saving type electric dust-cleaning apparatus high-frequency pulse power controlling device

The utility model relates to a power saving electric precipitator using high-frequency impulsing power source and controlling device, which comprises an electric precipitator, a high-frequency impulsing transformer, a high-frequency inversion circuit, an amplitude modulation circuit, a triphasic rectifier filter circuit, and a multi-CPU controlling unit. The electric precipitator, the high-frequency impulsing transformer, the high-frequency inversion circuit, the amplitude modulation circuit and the triphasic rectifier filter circuit are connected consecutively. The utility model makes best use of the capacity characteristic of the electric precipitator and the inductance characteristic of the high-frequency transformer, and is capable of regularly providing the electric precipitator high power electric source and low power electric source under the control of the multi-CPU controlling unit.
