ABSTRACT:
The invention is an over voltage protector for A.C. power. A single transistor is connected through a diode bridge to one line of the input power. The other side of the bridge network is connected through an output transformer to a common input and output. The base of the transistor is connected to a voltage source which may be provided by either a rectified input signal or a constantly charged capacitor located between the base and the emitter. A Zener diode connected through a diode bridge to the secondary winding of the output transformer is also connected across the base to an emitter. The breakdown voltage of the Zener diode controls the maximum voltage between the base to emitter, which consequently controls the A.C. output voltage.
