The inverter circuit consists of low-frequency oscillator, buffer and push-pull amplifier output circuit, the circuit is shown as the chart. Low-frequency oscillator is composed of two NOT gate circuits D1, D2 which is inside of NOT gate IC (D1 ~ D4), resistor R1, potentiometer RP and capacitor C. Buffer is composed of two NOT gate circuits D3, D4 which is inside of NOT gate IC (D1 ~ D4) and resistors R2, R3. Push-pull output circuit is composed of Zener diodes VS1, VS2, VM0S field-effect transistors VF1, VF2 and transformer T. Resistor R4, Zener diode VS3, diode VD and IC form the power supply circuit. Light-emitting diode V1, resistor R5 form the working indicating circuit. R1 ~ R5 use 1/4W carbon film resistors or metal film resistors.
