This paper proposes a method of maximum power point tracking using adaptive fuzzy logic control for grid-connected photovoltaic systems. The system is composed of a boost converter and a single-phase inverter connected to a utility grid. The maximum power point tracking control is based on adaptive fuzzy logic to control a switch of a boost converter. Adaptive fuzzy logic controllers provide at...

Abstract An improved high voltage boost Z-source inverter topology is proposed to improve ability. Compared the conventional inverter, it can produce very with a short shoot-through duty ratio, stress on capacitors and inverter-bridge greatly reduced, has inherent limitation inrush current at startup. The addition of input capacitor an active switch allows in Z source network flow reverse direc...

This paper investigates the performance analysis of various Multicarrier Pulse Width Modulation strategies with Sinusoidal reference for single phase seven level diode clamped Z-source inverter designed with two intermediate Z-source networks connected between the input source and inverter circuit. The diode clamped Z-source based MLI strategy enhances the fundamental output voltage and reduces...

A simple and economical power conditioner to convert the power available from solar panels into 60 Hz ac voltage is described. The raw dc voltage from the solar panels is converted to a regulated dc voltage using a boost converter and a large capacitor and the dc output is then converted to 60 Hz ac using a bridge inverter. The ratio between the load current and the short-circuit current of a P...

A new topology of a hybrid distributed generator based on photovoltaic and wind-driven permanent magnet synchronous generator is proposed. In this generator, the sources are together connected to the grid with the help of only a single boost converter followed by an inverter. Thus, compared to earlier schemes, the proposed scheme has fewer power converters. Model of the proposed scheme in d-q a...

This paper proposes a new high step-up DC–DC converter designed especially for regulating the dc interface between various micro sources and a dc–ac inverter to electricity grid. The need of Electricity increases the power demand where the power demand met by the conventional sources of energy has some disadvantage of pollution, this disadvantage can be decreased by the use of the Renewable ene...
