Found in a 90s documentation, this circuit triggers the SCR when there is an overvoltage in order to cause the fuse to blow quickly. The SCR can be a TIC106.
In this oscillator a phase shift network formed by C1, C2, C3 and R1, R3, R4 determine the fase...
For inductive loads we have the configuration shown in the figure. Note that the optical coupler...
