Over voltage and Under Voltage Protection Circuit Protection circuits, like reverse polarity protection, short-circuit protection and over/under voltage protection, are used to protect any electronic appliance or circuit from any sudden mis-happening. Generally, fuse or MCB is used for overvoltage protection, here in this circuit, we will build an overvoltage protection circuit without using Fuse. Overvoltage protection is a power supply feature that cutoffs the supply whenever input voltage exceeds the preset value. For protection from high voltage surges, we always use overvoltage protection or a crowbar protection circuit. The crowbar protection circuit is a type of overvoltage protection that is most commonly used in electronic circuits. There are many different ways to protect your circuit from overvoltage. The simplest way is to connect the fuse at the input supply side. But the problem is that it’s one-time protection because as the voltage exceeds the preset value, the wire ins...
