This paper presents a method to control both the dc boost and ac output voltages of Z-source inverter using neural network controllers. The capacitor voltage of the Z-source network has been controlled linearly in order to improve the transient response of the dc boost voltage of the Z-source inverter. The peak value of the line to line ac output voltage is used to control and keep the ac outpu...

This paper proposes a family of novel enhanced-boost quasi-Z-source inverters (EB-qZSIs). For the similar input voltage and shoot-through duty ratio, to that Z-source inverter/enhanced-boost qZSIs, presented topologies provide very high boost at modulation index with improved quality output waveform. Compared EB-ZSI EB-qZSIs, these less capacitors stress, which reduce volume cost system. Akin t...

This paper presents the comparative study of various Multicarrier Pulse Width Modulation techniques with Sinusoidal reference for single phase seven level cascaded Z-source inverter designed with three intermediate Z-source networks connected between the input source inverter circuit. The cascaded Z-source based MLI technique enhances the fundamental output voltage and reduces the Total Harmoni...

Electronic loads are a family of power converters which can be used as a variable impedance load in different applications. This paper analyzes high efficiency zero-voltage electronic loads based on the quasi Z-source converter topology .The proposed topology operate as an ideal current source which enables the operation of the zero input voltage. It can achieve a high efficiency of more than 9...

In the present world, conventional sources of energy are depleting at a faster rate because of its increased consumption. Renewable sources of energy are the better alternatives for this problem and among this solar energy is the best solution. Among the various PV (photovoltaic) applications, water pumping system using solar energy is growing in interest in isolated areas, where grid availabil...
