H-bridge relay driver

 · Because of nature of the latching relay, no H-bridge is needed (although you can definitely use an H-bridge, but it would be wasteful). The circuit I have here uses an SN quad H-bridge driver chip. Only one of the four half-bridges is used.  · Motor Driver: H-Bridge Topology and Direction control The most commonly used actuator in any electronic device/machine will be motors next to solenoids, pneumatics and hydraulics. From a simple vibration motor inside a mobile phone to complex stepper motors in CNC machines, these DC machines can be found everywhere. Relay-MOSFET driver in this project is a simple circuit in which the H-bridge was constructed using two electromagnetic relays (EMR) used as 4 switches. They were used to control the spinning direction of the motor. Now to control the speed, an N-channel MOSFET IRFN was used for switching of the motor.

Here’s the concept of the H-bridge: A DC motor spins either backward or forward, depending on how you connect the plus and the minus. If you close switch 1 and 4, you have plus connected to the left side of the motor and minus to the other side. An H-bridge is a type of circuit that you can use to get a reversible DC motor to spin both clockwise and counterclockwise. In other words, this circuit allows you to quickly reverse the direction a motor is spinning by using a switch or controller chip to change its direction. The H-bridge latching relay driver circuit is much more complex, but uses the same principles as the simple standard relay driver circuit. Latching relays are useful because they only consume current when their state is changed.

Helicobacter pylori (H. pylori) is a type of bacteria that infects your stomach. An H. pylori infection may be found in more than half of the world’s population, although most do not realize they have it because they do not get sick from it.
