How to Make Crowbar Overvoltage Protection Circuit

Introduction

Protection of electronic components and the surroundings from high voltage is the most important thing to do. And therefore, engineers have designed the overvoltage protection module. Through the overvoltage protection circuit, it is workable to set a specified voltage threshold And, when the output of power supply voltage exceeds this value, the overvoltage protection circuit activates and the power supply works to pull down the overvoltage on its output. In this tutorial, we are going to “Crowbar Overvoltage Protection Module”.
