ABSTRACT:
An over voltage protector for AC power. Transistors are connected across the power line in a common base configuration with the transistor outputs being connected to the primary winding of an output transformer. A secondary winding of the output transformer in series with a zener diode is connected to the base of the transistors to prevent the output voltage across the primary winding from exceeding a predetermined level, positive or negative. A diode bridge allows current to flow in only one direction through the zener diode. Additional turns on the primary winding with a tap connection also provide voltage regulation.
