H-Bridge

An H-Bridge is a circuit topology that uses four switches (typically transistors or MOSFETs) arranged in an H-shaped configuration to control the direction of current flow through a load. It enables bidirectional control of DC motors by allowing current to flow in either direction, making the motor spin clockwise or counterclockwise. H-Bridges are commonly used in robotics, motor drivers, and power electronics applications where precise motor control and direction reversal are required.
