When a high DC voltage is applied to a capacitor with strongly asymmetrical electrodes, it generates a mechanical force that affects the whole capacitor. This phenomenon is most likely to be caused by the motion of ions generated around the smaller of the two electrodes and their subsequent interaction with the surrounding medium. A method to measure this force has been devised and used. A form...

Recently, the demand for switched-capacitor converters has increased due to use of a low voltage input source. This article aims improve some weak points these inverters, such as high number elements by presenting novel single-source step-up multi-level inverter topology. The proposed consists cell with self-balancing capability. converter uses DC source charge series capacitors stage increase ...

Renewable Energy based microgrids are being considered to provide electricity for the expanding energy demand in the grid distribution network and grid isolated areas. The technical challenges associated with the operation and controls are immense. Electricity generation by Renewable Energy Sources is of stochastic nature such that there is a demand for regulation of voltage output in order to ...

This paper presents a novel methodology using coupled inductor for hybridizing multi input sources. A four port three input dc-dc converter is chosen, two photovoltaic sources and a storage medium are interfaced with the converter. The two sources can supply the load as well as charge the battery. Four independently controlled switches are employed to provide dc regulated output. The hybridizat...

The source frequency has a strong influence on plasma characteristics in RF discharges. Multiple sources at widely different frequencies are often simultaneously used to separately optimize the magnitude and energy of ion fluxes to the substrate. In doing so, the sources are relatively independent of each other. These sources can, however, nonlinearly interact if the frequencies are sufficientl...

In this paper, a perturb and observe (P&O) based voltage regulator (POVR) capacitor compensator (CC) circuit are proposed for the implementation on 31-level asymmetrical switch-diode multi-level DC-link (MLDCL) inverter. Since application of MLDCL in standalone photovoltaic (PV) system requires constant DC voltages from PV panels, POVR strategy is deployed to regulate along with capability deli...

A proof of the theorem giving maximum available active power with constant transmission losses (i.e., efficiency) valid for arbitrary waveforms, is proposed. This makes it possible to rigorously generalize definitions factor based on definition apparent as apply them systems non-symmetric, non-sinusoidal, and eventually time-varying non-periodic) waveforms or DC grids, thus extending its applic...

Sensitive equipment and non-linear loads are now more common in both the industrial/commercial sectors and the domestic environment. Because of this a heightened awareness of power quality is developing among electricity users. Therefore, power quality is an issue that is becoming increasingly important to electricity consumers at all levels of usage. Continuous variation of single-phase loads ...
