  • Overvoltage protector
    Patent number: 5883775
    Abstract: An overvoltage protection circuit passes all the normal operating voltages and limits the peak voltage increase during a lightning impulse to a level comparable to the battery voltage. Normal operating voltages of 200 V peak are passed and under lightning impulse conditions the voltage increase is limited to about 90 V. The circuit has first and second protectors connected in series, the first protector being a standard thyristor protector and the second being a gated bidirectional thyristor connected to a diode and a capacitor.
