Solution:

• A full bridge single phase inverter is a switching device that generates a square wave AC output voltage on the application of DC input by adjusting the switch turning ON and OFF based on the appropriate switching sequence, where the output voltage generated is of the form ?, -Vdc, Or 0.
• Load commutation mode is a technique used in single-phase full bridge inverters to achieve energy transfer from DC to AC in a load.
• In this mode, the load current is commutated to a different load branch by turning off the thyristor in the original load branch.
• The single-phase full bridge inverter can operate in load-commutation mode only if the load is RLC underdamped.
• Second order under damped circuits are used when LOAD commutation is required.
