Circuit principle 12v to 110v inverter

Circuit principle 12v to 110v inverter: The power inverter field effect transistor as the inverter device. Car battery for power supply. Therefore, when the input voltage is 12 volts DC. The output voltage is 100V AC's. However, the input and output voltage is not limited to this. You can use any voltage. They rely on transformers. The output is a square wave. According to experience, this circuit approximately 100W power. Circuit must be installed by a fuse, because too much input current flows, the oscillator is stopped.
