For the best designing, you need to know about each and every detail.Įvery Person nowadays is familiar with the term Relay relays are most commonly used for switching purposes and are also used for protection. You should know exactly which are the normally closed and normally open legs, which are the legs of the coil and which is the common leg. So now we will start designing the H bridge relay circuit using only two relays.įor the relays based H Bridge, you should have complete knowledge of the Relay and its pins. So this way no matter which relay you turn on first or you turn ON both the relays at the same time, there will be no short circuit. To get rid of this risk we can also make an H bridge using only two relays. The same can happen with the relays or switches S3 and S4. We can use 4 relays to control the polarity of the voltage which is supplied to the DC Motor, but as I said using 4 switches or relays there is high risk when the switches S1 and S2 or turned On both at the same time, which results in the short circuit. This applies only when you use 4 switches.Īs this tutorial is about the relay h bridge so I will now talk about the relays only. If you do so it will short the voltage and ground. One thing that you should always take care off switches S1 and S2 should never be closed “Turned ON” both at the same time and similarly for S3 and S4. So I hope now you have a basic understanding of what is an h bridge and how it works. Now if the above two images are combines you will see it makes H. Now you can see the right terminal of the motor is connected with the Voltage while the left terminal of the motor is connected with the ground. Now if the switches S2 and S3 are closed. The left terminal of the motor is connected with the Voltage while the right side is connected with the ground. The flow of current can be seen in the picture below.
The switches S1, S2, S3, and S4 are used to change the polarity of the voltage supplied to the DC Motor. An H bridge can be build using four switches, Mosfets or Relays. Let me explain this in very simple words, the term H Bridge is derived from the flow of current in the circuit which you will understand completely with the help of the following example. The term H Bridge is actually the typical graphical representation of the circuit. H bridges are also used in industries to Allow High Ampere DC Motors to run Forward and backward.Īs slowly and gradually we start understanding the H Bridge and its uses, some questions start to pop up in our minds like for example the most basic question that you also might be thinking about is, Why H is used? What does it mean? H-bridges are most commonly used in robotics for the Forward, Left, Right, and Reverse Movement. The H-Bridge is basically an electronic circuit that is used to change the polarity of the voltage applied to the load. I would appreciate your support in this way!

How to start designing the Relay H Bridge?.This is the only tutorial throughout the world which explains the designing steps from nothing to the final working product. If you really want to learn how to design something from scratch when there is nothing. If you only need the circuit diagram and programming then you can jump to the circuit diagram and programming section, but trust me this will never help you learn the designing.
