H Bridge Design. These switches can then be used to control the direction of current running from the dc source to ground in either direction across the connected impedance. We will see the h bridge circuit design applications advantages.
An h bridge is a set of four switches that are assembled in such a way that an arbitrary load impedance is decoupled from a direct current dc power rail and ground. These switches can then be used to control the direction of current running from the dc source to ground in either direction across the connected impedance. There are various h bridge designs and some use discrete components consisting of mosfets while other designs utilize a dedicated integrated chip ic h bridge.
We will see the h bridge circuit design applications advantages.
In the most simplistic terms an h bridge circuit can switch the polarity of the attached load. Here you will see how an h bridge circuit works. An h bridge is a set of four switches that are assembled in such a way that an arbitrary load impedance is decoupled from a direct current dc power rail and ground. If q1 and q4 are turned on the left lead of the motor will be connected to the power supply while the right lead is connected to ground.
