Full Bridge Inverter
The general concept of a full bridge inverter is to alternate the polarity of voltage across the load by operating two switches at a time. Positive input voltage will appear across the load by the operation of T1 and T2 for a half time period. The polarity of voltage across load will be changed for the other half period by operating T3 and T4.
