Analysis Of Grid-Connected Photovoltaic Systems

Conventionally, grid connected photovoltaic energy conversion systems are composed of a DC-DC converter and an inverter. The DC-DC converter is controlled to track the maximum power point of the photovoltaic array and the inverter is controlled to produce current in such a way that the system current has low Total Harmonic Distortion (THD) and it is in phase with the utility voltage. The efficiency of the conventional system is low because the DC-DC converter and the inverter are connected in series. The purpose of this article is to design a photovoltaic generation system for connection in a three-phase system using only a DC/AC inverter... - Dr. L Ashok Kumar

Performance Evaluation

In previous publications, authors have reported about the performance of the single-phase inverter topology based on controlled charging of the capacitor. The dynamic performance was not available. This article presents the dynamic performance of the inverter for various types of load, which includes leading, lagging and unity power factor, and analysis for 'total harmonic distortion' has been included... - K.Vijayakumar, S.Kannan and S.Ponnayira Sundaravel

Inverter Heart of solar system

India is one of the fastest growing economies in the world like China, South Africa, Russia and Brazil. It is the second largest country in the world as far as population is concerned and fifth largest country in the world after USA, China, Russia and Japan as far as electricity generation is concerned, in spite of that its per capita power consumption is merely 920 units. There is a huge gap in power generation and peak power demand. Renewable energy is one of the most viable solutions as we are facing serious consequences of global warming all around the globe. - Aqeel Ahmad
