H Bridge Diode Circuit. If you re not sure how the transistor works i recommend you read the article how transistors work first. Since there are multiple current pathways there must be four diodes to provide a path for the induced voltage as shown in figure 5.
These circuits are often used in robotics and other applications to allow dc motors to run forwards or backwards. The circuit network that accomplishes the above procedure is called a bootstrapping network in an h bridge circuit. You can build an h bridge with four transistors.

An h bridge is an electronic circuit that switches the polarity of a voltage applied to a load. A diode bridge is an arrangement of four or more diodes in a bridge circuit configuration that provides the same polarity of output for either polarity of input. When used in its most common application for conversion of an alternating current ac input into a direct current dc output it is known as a bridge rectifier a bridge rectifier provides full wave rectification from a two wire. Using your diagram of the h bridge you have to consider the battery as an effective short circuit the battery internal resistance being extremely low.
