A common use of the H bridge is an inverter.

An H bridge is built with four switches (solid-state or mechanical).

H bridges are available as integrated circuits, or can be built from discrete components.

The term H bridge is derived from the typical graphical representation of such a circuit.

A variety of low and high side switches, switch drivers and H bridges are illustrated.

An H bridge is an electronic circuit that enables a voltage to be applied across a load in either direction.

The H bridge with a DC supply will generate a square wave voltage waveform across the load.

A "double pole double throw" relay can generally achieve the same electrical functionality as an H bridge (considering the usual function of the device).

Their design is a branch of power electronics, usually based on a three-phase MOSFET H bridge.

The half-H bridge type is commonly abbreviated to "Half-H" to distinguish it from full ("Full-H") H bridges.

An H bridge would be preferable to the relay where a smaller physical size, high speed switching, or low driving voltage is needed, or where the wearing out of mechanical parts is undesirable.

Another alternative replaces the half bridge MMC submodule described above, with a full bridge submodule containing four IGBTs in an H bridge arrangement, instead of two.

The smartphone effectively becomes a "remote control" allowing the user to dim the lights, open the curtains and play the movies, using a combination of Arduino circuit and actuators connected to the Internet via an H bridge.
