**6.2 DC/AC inverter**

The second stage of the inverter power supply is to invert the new DC level into AC voltage through DC/AC inverter. There are many different topologies for a DC/AC inverter. The most common topology is the full bridge configuration because of its easy filtering (Xue et al., 2004). The full-bridge inverter was chosen as the inverting output stage for a number of reasons. It is preferred over a half-bridge inverter because with an equivalent input voltage, the full-bridge inverter can provide twice the amount of output voltage. The full-bridge inverter is also significantly more controllable than other configurations. A single phase full bridge inverter is shown in Figure 10 and the function of the full bridge inverter is to convert the DC voltage supplied by DC/DC converter into a 100V, 60 Hz sine wave. The most important part of the DC/AC inversion process is in the generation of the sinusoidal 336 Grid Computing – Technology and Applications, Widespread Coverage and New Horizons
