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. [1]
Power modules are used for power conversion equipment such as industrial motor drives, embedded motor drives, uninterruptible power supplies, AC-DC power supplies and in welder power supplies. Power modules are also widely found in inverters for renewable energies as wind turbines, solar power panels, tidal power plants and electric vehicles (EVs).
In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i.e. to convert it from an unknown or alternating polarity to a direct current of known polarity. In some motor controllers, an H-bridge is used to control the direction the motor turns.
Half-Bridge can refer to: A single-direction configuration of an H-Bridge motor controller; A form of DC to DC converter switched-mode power supply. One of a pair of devices that connect to perform the Bridging (networking) function of a computer network
When the voltage rises above the normal range, the diodes become forward-biased (conducting). For example, diodes are used in (stepper motor and H-bridge) motor controller and relay circuits to de-energize coils rapidly without the damaging voltage spikes that would otherwise occur.

The cause of the Rainbow Bridge deadly vehicle explosion remains something of a mystery, with investigators now exploring whether a mechanical failure in the car could be to blame.
German firm Konig, who specialised in racing outboard motors, [6] built a few 1000cc H-8s in the 1970s, which were basically two of their VC500 flat fours mounted one above the other, with the direction of rotation reversed on one of them. Each half of the engine was a water cooled 2-stroke with rotating disc valve driven by a toothed belt via ...
