Capacitor C5 and potentiometer R12 figure out the frequency of the output signal at pin number 3 of IC1, the 555oscillator. The output signal is differentiated by C3 and C4 before it’s input to the base of power transistors Q1 and Q2 through diodes D1 and D2, respectively. The signal from IC1 is adjusted to 120 Hertz, because the flip-flop created by transistors Q3 and Q4 splits the frequency by two.
The following circuit Inverter 100W, simple to use and excellent ideas.
If we want to work with the electrical equipment outsite home that has a voltage 220Volt /AC 50HZ, that only have around 100Watt not exceed. Yo need Small power inverter around 100Watt. This inverter perform modify from work electrical power forces of electric battery 12 volt provide high voltage to work.
