A 13-Level Hybrid Multilevel Inverter Topology by Combining ANPC and Improved H-Bridge

The research on multilevel inverter has created a milestone due to its wide application areas starting from industries to smart grid systems. Due to the increase of power demands, the importance of inverters increases in the micro-grids and standalone systems. This paper presents a single phase hybrid cascaded structure of active neutral point clamped converter with modified H-bridge multilevel inverter. The five level active neutral point clamped converter is cascaded with nine level modified H-bridge to generate 13 level output voltage. This combinational structure reduces some source count by maintaining higher voltage levels. The mathematical analysis is provided with the simulation and experimental results for validation of the topology. The symmetrical source configuration is implemented for the voltage level generation. The series combination of resistive inductive is considered in the load side. This structure is well suited for the PV applications where the inverter structure can be cascaded for increased power level.
