Add This Short Circuit Protection To Your Power Supply Short circuit protection for variable power supply circuit. if you are having a variable power supply and want the short circuit operation to work even at voltages below 3 v or 1.5 v, then you can try adding the following short circuit protection circuit to your power supply circuit. the idea was designed and submitted by one of the avid. Step 1: understanding the circuit. the circuit is really easy to understand. a resistor of low value (the resistor value will be explained later) is connected in series with the output of the power supply. as current starts to flow through it, a small voltage drop will appear on it and we will use this voltage drop to determine whether the.
Add This Short Circuit Protection To Your Power Supply вђ Short circuit and low load resistance protection. one intriguing aspect of this design is its proactive protection mechanism. in the event of a short circuit or an unreasonably low load resistance causing the output voltage to plummet below the predefined value, the power supply system takes action. Adding overload short circuit protection. a simple inclusion of t3 and r2 enables the bench power supply circuit design to be 100% short circuit proof and current controlled. with this design even an intentional shorting at the output will not cause any harm to the t1. the working of this stage could be understood as follows:. Step# 02. then in the next step, we have to connect this circuit to the power supply. for this, we have to make the cut between the negative wire of the supply and connect the relay coil pins in series with the power supply. also, you have to connect the relay common pin and coil pin. now, your circuit is ready to test. A short circuit protection diagram outlines the steps that need to be taken to prevent such an event from occurring. for example, it specifies the parts of the circuit and how they should be connected, how the wires should be installed, and the fuse ratings for each component. in most cases, the diagram will also include a list of safety.

Working of the circuit! the first component we need for the circuits is the relay which consists of a coil and to change over contacts that means that when no voltage is applied to the coil. when at least 3.8v is applied to the coil, the contacts open close. now, we can use one of the change contacts when there is no over current and open the. 5. this circuit looks relatively simple to build. i'm not going to bother with the transformer since i have a dc adapter. i was wondering how would i adapt this circuit to use a lm317 instead of a 7805. the maximum output is 1.5a. i presume i would need beefier transistors. however am unsure as the formulas at the bottom i never seen in my life.
