In the circuit shown as the chart, V1 ~ V4 are two composite switch amplifier tubes, of which V2 and V4 can be made by a few high-power tubes in parallel according to the power requirements of the inverter. B is the step-up transformer. Adjusting the resistance of RP could make the pin 3,4 IC output high and low frequency with 50Hz alternately. When the pin 3 outputs high level, VT1, VT2 are in saturation, VT3, VT4 end, when the pin 4 outputs high level, VT3, VT4 are in saturation, VT1, VT2 are closed. So the transformer generates electricity in two windings of the primary coil, the secondary coil can sense 220V, 50Hz square-wave voltage.
