Abstract— In this paper, the indirect matrix converter is
systematically studied with the single-pole-multiple-pole
representation. A carrier based PWM algorithm is developed
in two steps. First, the continuous modulation functions for all
the throws are derived based on the desired sinusoid ....etc

ABSTRACT

The rectifier and inverter are used in vector control of induction motor. The most shortcomings are that exist a big capacitor and energy pass only from power sources to load. This paper details a novel matrix converter-indirect matrix converter. It is used in vector controlling research of induction motor and displaced for conventional inverter to supply power for induction motor. Because switches are bidirectional in the rectifier, it can realize bidirectional pass of the energy and decrease pollution of harmonic wave. Meanwhile ....etc

The world is surely and steadily moving towards the newer generation of direction injection diesels, be it unit injected or common-railed. Mercedes Benz had already introduced the common rail engine in India a few years back but then they are the technology leaders worldwide and augur no comparisons. so. it was a matter of time before one of the other car manufacturers in India took up the challenge and introduced the engine in a car that could be available to a much larger segment of the car-buying populace.

As it has done on a number of ....etc

The Idea Of Direct Memory Access
By providing circuitry to generate addresses and memory control signals independently of the processor we see that it is possible to improve performance considerably. All that is necessary is to provide a signal to tell the processor to remove itself from the bus so there is no contention on the memory control, address, or data lines.

This is the entire concept behind direct memory access (DMA). To complete our picture, it is important to note that there are actually several ways that DMA can be ....etc

Gasoline direct injection or GDI is a variant of fuel injection employed in modern four stroke petrol engines. The gasoline or biobutanol is injected right into the combustion chamber of each cylinder, as opposed to conventional multi point fuel injection that happens in the intake manifold.

GDI enables stratified charge (ultra lean burn) combustion for improved fuel efficiency and emission levels at low load. Further improving efficiency and high-load output-power, the engine power is governed by modulating fuel injection, like a diesel eng ....etc

Sensorless Indirect Stator Field Orientation Speed Control for Single-Phase Induction Motor Drive
Abstract
The industrial requirements for the control of an inductionmachine without a mechanical sensor continue to be ofinterest, as evidenced by the most recent publications. The focusis on improvements of control without a mechanical sensor. A newmethod for the implementation of a sensorless indirect stator-fluxorientedcontrol (ISFOC) of a single-phase induction motor (SPIM)drive is proposed in this paper. The proposed method of rotor ....etc

Direct to home (DTH) television is a wireless system for delivering television programs directly to the viewer's house. In DTH television, the broadcast signals are transmitted from satellites orbiting the Earth to the viewer's house. Each satellite is located approximately 35,700 km above the Earth in geosynchronous orbit. These satellites receive the signals from the broadcast stations located on Earth and rebroadcast them to the Earth.

The viewer's dish picks up the signal from the satellite and passes it on to the receiver l ....etc

ABSTRACT
Indirect field orientation (IFO) induction machine drives are increasingly employed in industrial drivesystems, but the drive performance is often degrades. Motor works on best performance at certain voltageand frequency for certain loads. In this paper artificial neural network is used to predict the operatingvoltage and frequency when the load torque and speed going changed so motor efficiency is increased.Simulation and experimental results are shown to validate the scheme.

The need for high energy density, lightweight power sources for demanding portable applications gives incentive to the search for novel fuel cell concepts and approaches that reduce size, weight, and system complexity. Such power sources would find applications in variety of portable medical devices, computer hardware, and military equipment. This talk addresses a direct methanol fuel cell (DMFC) system approach wherein the fuel (methanol) and air are mixed and fed simultaneously to anodes and cathodes of the fuel cell stack. This overall appro ....etc
