Over voltage protection circuit diagram.

The zener diode is chosen to be slightly higher; This protection circuit acts as a voltage regulator and also circuit breaker, we have 5v load and hence we have used 5.1v zener diode, you can choose zener diode voltage range depends on your load or device voltage range. A “crowbar” circuit (shown in figure 1) can protect your device from overvoltage.

Here is a simple over voltage protector circuit that breaks the power to the load if the voltage increases above the preset level. Overvoltage autocut circuit diagram this autocut circuit is very easy, simple and very useful. As the name implies, the circuit offers protection from high voltages and it handles temperature compensation for analog chips.

Thus this circuit will not only cut off during low voltages but also will provide a total over voltage protection to the entire house or premises. The circuit may be used as a home protection system and installed inside the existing main switch board with the relay contacts connected in series with the mains supply line. The device is designed to sense an overvoltage condition and quickly disconnect the input voltage supply from the load before any.

A very simple dc over voltage protector circuit is shown below. Inductor l and capacitor c provides protection to scr against large dv/dt and di/dt. You can even change the zener diode according to your suitable voltage value.

The power will be restored only if the voltage drops to normal level. The circuit detailed in figure 1 is configured to activate at 19.2v although an arbitrary cut of level could be opted which may be figured out using the following equations: The circuit uses the following components:

When the v1 reaches 6.8v, the output will be protected. This kind of circuit is used in voltage stabilizers as over load protection. The transistor is set to monitor the input voltage applied to it from the left, in case the voltage rises above a specified limit, the transistor conducts, providing the required current to the scr, which instantly fires, shorting the output and thus protecting the load from the hazard.
