Rated working voltage of the capacitor is typically 1800 ~ 2200V, electrical capacity 0.8 ~ 1.2μF, and the internal impedance of the capacitor and then have a 10 ~ 12MΩ resistance, and its role is to automatically discharge the charge on the capacitor after the shutdown.pyqservice manual download site
The main role of the high-voltage capacitor and high voltage diode is half-wave voltage doubler rectifier circuit to provide a DC magnetron anode voltage. High-voltage high-voltage transformer secondary winding of the output AC voltage 2100V or so, after the high-voltage and high-voltage capacitor voltage doubler rectifier diode, to get around 4000V DC high voltage supplied to the magnetron male (female) poles. Due to the magnetron cathode including anode outside, for safety, the circuit is usually always magnetron anode grounded, while the cathode to the negative pressures.pyqservice manual download site
There are high-voltage capacitor circuit of the microwave oven to improve the efficiency effects. Because lag presence of leakage magnetic flux leakage current transformer work, less efficient; With high voltage capacitor, its advanced capacitive current will lag compensation leakage currents play a role, and thus make the power factor of the circuit can be improved, efficiency rise.pyqservice manual download site
