Modeling and Analysis of a Novel Boost Derived Multilevel Hybrid Converter

Multilevel inverters (MLI) offer high power capability connected with lower output harmonics and lower conduction and switching losses. Conventional cascaded H-bridge (CHB) MLI produces AC output which can be employed for a single load. But for smart residential nanogrid applications, dual load (AC and DC) is required concurrently. This paper has introduced a new topology of boost derived multilevel hybrid converter (BDMHC) which produces multilevel AC and DC output simultaneously. Thus the converter required the lesser number of switches to supply both AC and DC load. This proposed topology of BDMHC is constituted one H-bridge seven-level symmetrical MLI with three separate boost converters. State space mathematical model has been developed for the proposed converter and validated with simulated circuit using MATLAB/Simulink.
