An H-Bridge is a circuit of 4 switches allowing to select the direction of current flowing through a part. The simplest H-Bridge consists of four manually controlled switches:
When using a simple H-Bridge it is important to prevent switches to short the supply voltage. In commercially available H-Bridges additional circuits prevent accidental short circuits.
