In this paper a solar photovoltaic (PV) system with maximum power point tracking (MPPT) for domestic low applications. The proposed contains PV array which provides electrical power, while DC/DC converter is incorporated to regulate the derived from panels. Fuzzy logic control (FLC) based MPPT has been proposed. To convert DC voltages and currents obtained Solar panels AC currents, Neutral clam...

The main objective of this paper is to control the speed of an induction motor by changing the frequency using three level diode clamped multilevel inverter. To obtain high quality sinusoidal output voltage with reduced harmonics distortion, multicarrier PWM control scheme is proposed for diode clamped multilevel inverter. This method is implemented by changing the supply voltage and frequency ...

We present a new technique for choosing spatial regions for X-ray spectroscopy, called " contour binning ". The method chooses regions by following contours on a smoothed image of the object. In addition we re-explore a simple method for adaptively smoothing X-ray images according to the local count rate, we term " accumulative smoothing " , which is a generalisation of the method used by FADAP...

In this paper, the vibrations of thin plate in modified couple stress thermoelastic medium by using Kirchhoff- Love plate theory has been investigated. The governing equations of motion and heat conduction equation for Lord Shulman (L-S) [1] theory are written with the help of Kirchhoff- Love plate theory. The thermoelastic damping of micro-beam resonators is analyzed by using the normal mode a...

This article investigates the multifrequency switching oscillations of silicon carbide (SiC) MOSFETs in three-level active neutral-point-clamped (3L-ANPC) inverters under three typical commutation modes (i.e., full mode, outer and inner mode). Multiple switching-oscillation components with various frequencies are identified theoretically for both full- outer-mode commutations, due to their swit...
