reverse voltage protection circuit

Reverse voltage protection circuit. Have you ever had an electronic circuit for which battery installation or current source should not be inverted or maybe if the reverse will result in a fast broken buddy

This time the admin will provide a solution. The circuit below is composed of 4 pieces of diode called a diode bridge circuit and can be used as a reverse voltage safety circuit

create a reverse voltage protection circuit

The reverse voltage safety circuit serves to secure voltage-sensitive equipment such as ic, transistor, and other sensitive components

understanding and the working of the transistor

Unlike the lights that have no poles, for ordinary incandescent lights it does not require this circuit

If my friend will make a logic gate circuit or other digital circuit then this circuit is mandatory pairs

The components needed to make a reverse voltage safety circuit are 4 pieces of diodes arranged to form a Bridge diode

For the + sign is connected to the + negative circuit + pole

For the other ends there are 2 pieces on connect battery or power source

with this circuit then if the battery or the source of the power supply is reversed then it will not be a problem in the electronics circuit that my friend plug and electronics circuit of course remain safe from damage

reverse voltage protection circuit scheme

Here is a reverse voltage circuit scheme

The above circuit can be mounted on the circuit which is sensitive to positive negative pole

In accordance with the workings of diodes that diodes only deliver if given the forward bias whereas if the bias backwards then the diode will be like an electrical insulator

For how diodes work please read on understanding and how the diodes work

How reverse voltage safety circuit Work

reverse voltage protection circuit is composed of 4 pieces of diodes to form a bridge diode as shown below

´┐╝reverse voltage safety circuit

For diode size using silicon type diode, the bigger the diode the better the example diode 5A or 10A or can also use a kiprok

In the above circuit from any current flows then at the + and negative poles output – remain the same

  • When A becomes positive pole and B becomes negative pole then electric current will flow from A ==> D4 ==> C ==> Load ==> D ==> D2 ==> B
  • When B becomes positive pole and A becomes negative pole then the electric current will flow from B ==> D3 ==> C ==> Load ==> D ==> D1 ==> A

In the above circuit although the poles at the input are changed then at the output pin C remains the positive pole and pin D remains the negative pole

The above circuit we often encounter on adapter equipment or any equipment that uses ac currents
