Found in 1965s General Electric documentation, this circuit is intended for the control of servos connected to the power grid. Equivalent modern components can be employed.
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...
