♔♔♔ An H-bridge is an electronic circuit which enables a voltage to be applied across a load in either direction. H-Bridges Circuit are often used to control the speed, position or torque of DC and stepper motors. An H-bridge is built with four switches (solid-state or mechanical). It takes a DC supply voltage and provides 4-quadrant control to a load connected between two pairs of power switching transistors. Below schematic diagram shows the Basic H-Bridge Circuit Diagram.
