Abstract

In this paper presents the controlling the power of using quasi-Z source inverter for renewable source application. The proposed quasi z source is single stage DC to AC converter it delivered buck-boost operation with respect to input. These buck-boost converter is highly suitable compare to the normal dc to dc converter for photovoltaic applications. The proposed single stage converter are reliable and suitable for renewable energy source application. The source impedance quasi network offers high gain compare to the exciting system and reduced the total harmonic level. The quasi-z source followed by single phase H bridge converter uses to convert DC to AC with high reliability output. A proposed system-built Simulink and the hardware made for the open loop control. The conventional voltage and current source inverter have its own limitation of the output voltage low compare to the input source in the voltage source inverter, it is just opposite in the current source inverter. These limitations overcome by designed novel modified z source inverter was developed and controlled pulse using unipolar and bipolar concept. The output of the inverter after filter, it produces the less harmonics result 7.6% on fifth harmonics level compare with conventional inverter.

Keywords: Modified z source network, single phase inverter, quasi converter, grid integration .
