Over Voltage Protection Circuit Diagram Based on Relay

In this tutorial, you will learn how to make this over-voltage protection circuit. It requires fewer components and is very effective in overvoltage conditions. It will cost you around 3$ to 5$ depending on the quality of components. Overvoltage occurs when the voltage in a circuit is raised above its upper design limits. This condition […]

Over Current/Short Circuit Protection Using LM358 OPAMP

This is an adjustable over-current and Short circuit protection using LM358 OPAMP. In this article, we will see how you can make short circuit protection using LM358 OPAMP. A short circuit occurs when the current flowing in a circuit bypasses the load and flows from a path having the least or zero resistance. We can […]

Short Circuit Protection Using Relay For Batteries

In this tutorial, we will see how to make a short circuit protection using Relay. Many times accidentally terminals of batteries and other power supplies get short-circuited. Due to this, they get hot and start degrading. In the case of lithium-ion or lithium-polymer batteries, they may catch fire due to short-circuit or even get blast. […]
