Tapped Inductor Quasi-Z-source Inverter With High Inversion Gain
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 2
Abstract
This paper proposes a high inversion gain single stage boost inverter, which introduces a tapped inductor network into the traditional quasi-Z-source inverter (qZSI), called tapped inductor quasi-Z-source inverter (TL-qZSI). The tapped inductor network including one tapped inductor and two diodes and is used to replace one inductor of the traditional qZSI. Similar to the tapped inductor Z-source inverter (TL-ZSI), the proposed inverter can provide high inversion gain. TL-qZSI has all the merits of TL-ZSI except that it also features with continuous input current, common ground with the dc source, and reduced capacitor voltage stress. This paper analyses the circuit operation principle, boost inversion features and its control strategy. Simulation and Experimental results are provided to verify its effectiveness and demonstrate the real features of the proposed circuit.
