SCR Mini Power Inverter

This be Mini Power Inverter , by use SCR be main part electronics , perform Oscillator Generator 400Hz give Output 300V by use Voltage Input 12V Current 0.8A.
The only drawback with this circuit is that it might latch in the conducting state if the load is too heavy or if there is a short at the output, this requires some kind of protection, on the input line, in the form of a fuse or similar. The transformer used is a 10W mains type with 6V+6V windings on the SCR side and a 110V+110V windings, in series, at the output. Efficiency is 50% and the ideal load is equivalent to a 22k resistor, 5W. The output waveform is vaguely sinusoidal at a frequency of 400Hz.
