Efficiency Improvement of WCDMA Base Station Transmitters using Class-F power amplifiers

Muthuswamy Venkataramani



(ABSTRACT)
Universal Mobile Telecommunications Systems (UMTS) is the preferred third generation (3G) communication standard for mobile communications and will provide worldwide coverage, a convenient software technology and very high data rate. The high data rate, especially, requires the use of bandwidth-efficient modulation schemes such as Quadrature Phase Shift Keying (QPSK). But mo ....etc

Abstract-
A pulse skipping control strategy is proposed to improve efficiency of grid-tied inverters at light loads. To maximize the efficiency of pulse skipping operation mode, three key parameters are identified and optimized based on a loss model, which is developed to find the maximal efficiency points using a three-dimensional search technique. A 200W prototype inverter was setup to verify the proposed control strategy. The experimental results show that the proposed pulse skipping control strategy greatly impr ....etc

Abstract
Automotive engines reject a considerable amount of energy to the ambience through the exhaust gas. Significant reduction of engine fuel consumption could be attained by recovering of exhaust heat by using thermoelectric generators. One of the most important issues is to develop an efficient heat exchanger which provides optimal recovery of heat from exhaust gases. The work presents a design and performance measurements of a prototype therm ....etc

Good evening friends!!

I am Ravi kumar from Visakhpatnam doing B.E(Mechanical) final year. We decided to do a project on improving efficiency of boiler in thermal power plant. We chose thermal plant department in Visakhaptanm Steel Plant. We have submitted our project title in college which could not be changed.

But we learnt in plant from our guide that there is nothing in plant to do to improve boiler efficiency and he is neither supporting us.

Hence i want any of project ideas or already done project ....etc
