INPUT POWER SUPPLY APPARATUS OF POWER SUPPLY UNIT IN ELECTRIC PRECIPITATOR

摘要

PURPOSE: An input power supply apparatus of a power supply unit in an electric precipitator is provided to prevent operation error of Micom due to noise caused by discharging error of an air purifying filter by not directly connecting input voltage with a main PCB, and cause no power consumption by using voltage generated by a temperature difference not using a separate power source. CONSTITUTION: The input power apparatus comprises a voltage generation part (10) in which an electromotive force is generated by a temperature difference between both ends of a thermocouple (12) so as to generate an input voltage for output of the high voltage, and a voltage increasing part (20) in which the voltage generated from the voltage generation part (10) is increased in a power supply unit in an electric precipitator in which a high voltage is impressed on an ionizing part and a duct collecting part for collecting dusts by discharging of a high voltage.
