ABSTRACT:
Within an oscillator circuit of the type wherein positive or negative current is recurrently directed to the gate of a GTO device when the charge voltage levels across first and second capacitors respectively reach trigger levels, voltage sensing circuitry is incorporated to insure that the capacitors are charged during independent periods of time so that the duration of each portion in the frequency cycles is separately controllable.
