English Abstract
Inverters are used widely nowadays because of many of renewable energy source available.
These energy source can provide DC voltage like solar panels and the real need of storage energy devices as batteries which also provide DC voltage.
Traditional DC-AC inverters have main limitation, this limitation is that AC output voltage is limited below and cannot exceed the DC-rail voltage.
To overcome this limitation and usage of transformer for boosting; in this thesis I explained briefly the Z-source network technique in inverters which can work buck/boost and inverting in one stage without needing to boost DC firstly and then invert or use the same DC to invert and then use transformer to boost.
Later Quasi-Z-Source network was developed, to operate better than Z-Source inverter by lower component ratings, reduced voltage stress, reduced component count and simplified control strategies.
It is common that the M (Modulation index) plays the unique effector in controlling Quasi-ZSource inverters and Do (Shoot through duty cycle) is related to M ; this thesis separates M & Do as each of them is output control signal of controller .This step added more limitation to component rating because of reducing the current in inductors to half.
Fuzzy Logic control used as a controller for the inverter .This thesis used mamdani method with 3 VDC ,IDC and Vc1 input and 2 outputs M and Do ,and centroid method of defuzzification was used .The designed inverter in this thesis could keep the output voltage 208 AC rms 60 Hz with wide range of variable DC input (200-400) v DC.
