Ignition system utilizing a saturable-core square wave oscillator circuit

Abstract: An improved saturable-core transistor oscillator circuit for feeding a negative resistance characteristic load. It includes a Jensen-type oscillator that has an added saturation winding to control starting and time duration of the oscillation. There is a high turns ratio output transformer connected to the load and a saturable-core transformer in the oscillator. And, the electromagnetic characteristics of the output transformer are set to resonate with the output at no load in order to provide high starting voltage, while the electromagnetic characteristics of the saturable-core transformer are set to provide an increase in the oscillator frequency as the load increases in order to reduce the output voltage so as to compensate for the negative resistance effect of the load.

Simulating oscillators using SPICE

Abstract: SPICE generation of the output signals from electronic oscillator circuits is obtained by transient analysis. Simulation success is software specific and depends upon how the transient analysis function is configured. Different tricks, which are oscillator configuration specific, may be applied to achieve simulation output. In the final analysis, one must remember that simulation is not a complete and full replacement for circuit construction and testing. Accurate analysis is given for resonant or relaxation circuits.
