PV array is increasingly employed for water pumping system. In this paper, the developed boost converter steps up the voltage produced by the PV array to a value which is suitable to run a single-phase induction motor. The inverter converts DC to AC is controlled by using sinusoidal pulse width modulation (SPWM) technique. By using a LCfilter the harmonics are eliminated and pure sine wave is o...

As an agriculturally based country, many rivers pumping stations are implemented in Myanmar. Currently, these operated with utility supply or diesel engines. For reliable energy and cost saving, the solar powered river now carried out Most of located at dry zones especially Magway, Mandalay Sagaing Divisions. The main problem station is harmonic induced due to DC/DC boost converter three phase ...

In this work, an efficient control scheme for a double stage pumping system is proposed. On the DC side, three-level boost converter employed to maximize photovoltaic power and step-up DC-link voltage. For maximum point tracking, classical incremental conductance method substituted by fuzzy logic controller. The designed controller estimates optimal step size which speeds up tracking process im...

In this paper, a new robust model predictive control (RMPC) for uncertain nonlinear systems subject to actuator saturation is designed regulate the terminal voltage of photovoltaic generator (PVG) that feeds DC motor-pump via buck DC–DC converter. The considered system combination PVG-converter and motor-pump, which possesses behavior along with under saturating signal highly dependent on opera...

We propose a random matrix theory to describe the influence of a time-dependent external field on electron transport through open quantum dots. We describe the generation of the current by an oscillating field for the dot, connected to two leads with equal chemical potentials. For low-frequency fields, our results correspond to adiabatic charge pumping. Finite current can be produced if the sys...
