Emergency Power

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

Today’s power scenario in the world and in India in particular has changed from that of 'Generation, Transmission,Distribution' to 'Generation, Storage, Distribution & Effective usage'. Solar power generation especially at the last milestone has been recognised as the need of the hour and though, India has not woken up to the effective storage and efficient use of power, the world at large is seriously looking at these dimensions. - S V Rao

The quality of power is most significant in the field of the power system. Many techniques are used for improving the same. In this article, the quality of the Power and THD values for different switching pulses are to be analyzed. Here, the existing system comprises a Solar Photovoltaic array, boost converter, Multilevel inverter with normal switching pulse, and RLC Load. The proposed system comprises a solar photovoltaic array fed multilevel inverter with Pseudorandom Binary Switching (PRBS) pulse, buck-boost converter, and three-phase induction motor. The Pseudo-Random Binary Sequence generator consists of shift register and logic gates...

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
