An H-Bridge circuit contains four switching elements, transistors or MOSFETs, with the motor at the center forming an H-like configuration. By activating two particular switches at the same time we can change the direction of the current flow, thus change the rotation direction of the motor.Click to see full answer. Keeping this in view, what is H bridge motor driver?An H bridge is an electronic circuit that switches the polarity of a voltage applied to a load. These circuits are often used in robotics and other applications to allow DC motors to run forwards or backwards.Similarly, what is H bridge with MOSFETs? An H-bridge is a circuit configuration commonly used to control the speed and direction of a brushed DC motor. In the circuit diagram we see that the 4 mosfets surrounding the motor form an “H” shape. The mosfets are used as switches and are activated in diagonal pairs. In respect to this, how does motor driver work? Motor drivers acts as an interface between the motors and the control circuits. Motor require high amount of current whereas the controller circuit works on low current signals. So the function of motor drivers is to take a low-current control signal and then turn it into a higher-current signal that can drive a motor.Why diodes are used in H bridge?The MOSFETs of the H-Bridge acts as switches which can be used to control the speed of the motor, as well as the rotational direction. The diodes represented in the H-Bridge are called “fly back diodes.” These diodes provide a path for the current to dissipate when the motor switches from on to off.
