SCR Inverter circuit with BSTC1026

Only drawback with the circuit is that it might latch in the conducting state

SCR inverter circuit

if device 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 10Watt mains type with 6Vdc+6Vdc 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, 5Watt. Output waveform is vaguely sinusoidal at a frequency of 400Hz.
