This paper suggests quinary asymmetric inverter with coupled inductors and transformer,
and uses it in hybrid system including photovoltaic (PV) and wind. This inverter produces
twenty-five-level voltage in addition to merits of multilevel inverter, has only one DC source. Then,
it is adequate for hybrid systems, which prevents increasing DC-link and makes control of system
easy. Proposed structure also provides isolation in the system and the switch numbers are reduced in
this topology compared with other multilevel structures. In this system, battery is used as backup,
where PV and wind have complementary nature. The performance of proposed inverter and hybrid
system is validated with simulation results using MATLAB/SIMULINK software and experimental
results based PCI-1716 data acquisition system.
