The electric mosquito dispeller circuit is shown in figure 1, which consists of the high frequency oscillator circuit, triple voltage rectifier circuit and high voltage shock net DW. When the power supply switch SB is pressed, the high frequency oscillator, which consists of the triode VT and transformer T, is getting power and working, it switches the 3V DC into the 18kHz high frequency AC, then it is boosted to about 500V(which is got from the 2 terminals of L3) by T, and then it is boosted to 1500V by the diodes VD2~VD4 and capacitors C1~C3, the boosted voltage is added on the metal net DW.
