  • Oscillator improvement
    Patent number: 4818953
    Abstract: An improved oscillator circuit for avoiding core saturation without the need for auxiliary magnetic devices employs an emitter resistance for regulating base voltage, and a semiconductor base shunt for initiating transistor cut-off when the base voltage increases above the threshold voltage of the semiconductor shunt, the emitter resistance being preselected to activate the base shunt before the transformer core reaches saturation.
