Artificial Bee Colony Based Solar PV System with Z-Source Multilevel Inverter

In recent days there is a great advancement takes place in the field of power conversion. There are so many novel converters are in practice whose performance is very good and that's why they attract the users for its maximal use. In most of the cases DC to AC power conversion is done by multilevel inverters (MLIs) in industries for higher rating requirements. MLIs are in demand these days because of its efficient operation and modular nature. In this work first of all best PWM switching strategy is finalized. Then this switching strategy is applied on all the three basic MLIs i.e. Diode Clamped (DC), Flying Capacitor(FC) and Cascaded MLIs. Comparison is also made among these MLIs regarding THD and no. of components required. In the last best switching with optimized topology is applied on z-Source MLI consisting Artificial Bee Colony optimization technique in Solar PV system. Finally a converter of very less THD is achieved with all the advantages of switching, MPPT, z-Source and Cascaded Multilevel inverters.
