This research paper presents a study of temperature reducing of high voltage switching power supply circuit of electrostatic air cleaner by the application of thermoelectricity as this air cleaner uses electric field’s force technique based on electrostatic precipitator (ESP) and high voltage with direct current to switch power supply. The power supply is based on a fly-back converter. The converter is designed to operate at high frequency with more than 19 kHz while Power MOSFET is switching the device through high voltage high frequency fly-back transformer#TLF14649. The circuit is capable of generating up to 4 kVdc for ionization part and collector part in air filter. The problem incurred is the heat coming up in high voltage switching power supply resulting in high consumption rate of electrical power. Therefore, the researcher tried to find a way to reduce the temperature of high voltage switching power supply by using cool air produced from thermoelectricity to observe its electrical power consumption rate. In testing, we measured temperature at high voltage switching power supply circuit and the electrical power consumption rate of air filter before and after the installation of cool air production system from thermoelectricity. The testing result appears that before installation, cool air production system from thermoelectric temperature is 27 and power consumption is 26.7W, while after the installation of cool air production system from thermoelectricity, the temperature is 23 and power consumption is 22.9W. Therefore, it is concluded that cool air production system from thermoelectricity can reduce the temperature and reduce electric consumption power of air filter resulting in lessening electricity bills. In future, the researcher will develop an application of cool air system from thermoelectricity to reduce temperature in other industrial systems to cut down electrical consumption of the country.
