The performance of D-STATCOM depends on capacitor voltage regulation. In D-STATCOM, the nonlinear controller is preferred to linear controller. Regulating and fixing the capacitor DC voltage in DSTATCOM can improve the system dynamic such as capacitor voltage response, current response and modulation index. The regulation of DC capacitor voltage based on optimal PI co-efficient. In conventional...

Analytic calculations of the electric field of a parallel-plate capacitor are notoriously difficult [1, 2, 3, 4, 5, 6, 7, 8]. The usual goal of such efforts is a calculation of the correction to the hard-edge approximation, C = A/4πd (in Gaussian units), of the capacitance for plates of area A separated by distance d. Calculate instead the electromagnetic momentum of the parallel-plate capacito...

This paper presents the analysis of single Miller capacitor feedforward compensation scheme which is used in threestage CMOS operational amplifiers. single Miller compensation capacitor in three-stage amplifiers can significantly reduce the total capacitor value, and therefore, the overall area of the amplifiers without influencing their stability. Feed forward technique is effectively combined...

Capacitor-couple technique used to lower snapbacktrigger voltage and to ensure uniform ESD current distribution in deep-submicron CMOS on-chip ESD protection circuit is proposed. The coupling capacitor is realized by a poly layer right under the wire-bonding metal pad without increasing extra layout area to the pad. A timing-original design model has been derived to calculate the capacitor-coup...

An electrolytic capacitors used as a decoupling reservoir which restrict the lifetime of photovoltaic (PV) micro inverters. This has led to the development of several improved decoupling circuits that can reduce the capacitor value to allow the use of non electrolytic types. The project focus on selection of the minimum decoupling capacitor value for the proper operation of discontinuous conduc...

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 is caused by the motion of ions generated around the smaller of the two electrodes and their subsequent interaction with the surrounding medium. If one of the electrodes is heated, it changes the conditions around the capacitor and influe...

Various inductive loads used in all industries deals with the problem of power factor improvement. Capacitor bank connected in shunt helps in maintaining the power factor closer to unity. They improve the electrical supply quality and increase the efficiency of the system. Also the line losses are also reduced. Shunt capacitor banks are less costly and can be installed anywhere. This paper deal...

In this paper, there is a combined approach which is used to compensate three stage amplifiers with ultra large capacitive loads and low power, using current mirror amplifier with split output is to decrease the occupied level of compensation capacitor that causes to lessen the occupied level of chip –area for using compensation capacitor and getting resulted in the light of better slew rate (S...
