Gram Sandesh Transmission-A Web Based Information System for Farmers

Image
Gram Sandesh Transmission-A Web Based Information System for Farmers Agriculture is the fortitude for our country India. A large population of the country depends on farming related activities for their sustenance. However, it is perceived that there is lack of a handy agronomical information system for the end users. Information and data is available but does not reach the end-user on time [1]. Safekeeping this fact into consideration; Gram Sandesh Transmission has been developed so as to facilitate the flow of useful information required for farming [2]. In last few decades the trade of farming has changed rapidly. Apart from the traditional problems in farming, farmers are now facing competition from global market. They strictly need to adhere quality standards set by World Health Organization to trade in international market. An era has arrived where key to success is accurate, timely information and accurate judgment placed upon it [2], [3]. Present generation predominan...

VOLTAGE-DOUBLE MAGNETICALLY COUPLED IMPEDANCE SOURCE NETWORKS

project center in trichy  A family of voltage-double magnetically coupled impedance source networks (VBMCISNs) is presented. The scheme of the proposed family is that adding the auxiliary capacitors and diodes to the magnetically coupled transformers to realize the voltage-double function. The proposed impedance networks can produce the higher voltage gain, reduce the voltage stresses across the passive components, have a common ground, realize the continuous input current and suppress the start-up inrush current. Finally, one of the resulting topologies is verified in the condition of DC-DC converter and DC-AC converter, theoretical analysis and experimental results are offered to verify the topology’s validity.

POWER ROUTING FOR CASCADED H-BRIDGE CONVERTERS

project center in trichy Modular power converters are expected to play a major role in medium and high voltage/power applications. Normally, each module processes the same amount of power, however this does not take into consideration that different modules can have a different remaining useful lifetime. This paper proposes the concept of power routing for cascaded H-bridge (CHB) converters, with the purpose of delaying the failure of the system. A third-harmonic injection into the duty cycles allows extending the imbalance capability of the structure, keeping the CHB operational even if some power paths are completely unloaded. Analytic investigation in conjunction with simulation and experimental measurements demonstrate the power routing by means of the proposed method.
