The main purpose of a voltage suppression circuit is to clamp the voltage to a safe level.

Dc voltage spike protection circuit.

The most common form of voltage clamping devices are metal oxide varistors mov s and zener diodes. Here in this circuit a 9v dc source is feeding the load which is a dc motor. Dc transient voltage suppressor circuit. Mov s are best suited for protection on bidirectional ac power supplies while zener diodes are best suited for smaller low energy dc supplies.

24 v dc 1 2 28 8 v dc. The tvs circuit we will build for dc power is shown below. The zener diode used is rated for 12v. To find the voltage rating of the mov allow for 20 headroom to account for voltage swell and power supply tolerances.

Given that no varistors have a voltage. Dc input circuits can experience current overload short circuit conditions or voltage transients esd etc and require ptcs multilayer varistors and fuse protection to meet regulatory standards or to ensure reliable operation. With the zener diode voltage chosen to be slightly above the maximum rail voltage under normal conditions it will not conduct. A lower clamping voltage indicates better protection but can sometimes result in a shorter life expectancy for the overall protective system.

This means that if the circuit were to receive voltage above 12v the zener diode would then break down and begin conducting. Another very simple form of over voltage protection uses an approach called voltage clamping. In its simplest form it can be provided by using a zener diode placed across the output of the regulated power supply.
