Advance electrical power networks are dominated by power electronic converters as these converters convert electrical power one form to another, e.g., DC-AC, DC-DC, AC-DC, and AC-AC. Since sustainable energy sources generate DC power, the voltage source inverter is widely adopted for DC-AC power conversion. As its peak AC output is always lacked behind the DC voltage source thus it always operates in buck mode. Thus, an additional DC-DC boost converter is connected to boost the output voltage at the desired level which ultimately increases the size and cost of the inverter system.
