Power system security enhancement is a major concern in the operation of power system. In this paper, the task of security enhancement is formulated as a multi-objective optimization problem with minimization of fuel cost and minimization of FACTS device investment cost as objectives. Generator active power, generator bus voltage magnitude and the reactance of Thyristor Controlled Series Capaci...

The use of switched capacitors as wide-range, programmable resistive elements in spatially extensive artificial dendritic trees (ADT's) is described. We show that silicon neuro-morphs with ADT's can produce impulse responses that last millions of times longer than the initiating impulse and that dynamical responses are tunable in both shape and duration over a wide range. The switched-capacitor...

Absfruct-A method of designing continuous-time active RC filters which employ only capacitors and FET transistors is presentedl. The effective RC time constants of these filters are determined by capacitor ratios. The filters employ switched resistors. These filters can uric any existing active RC or passive RC topology as the basis for the design and inherit the sensitivity properties of the c...

A switchable operational amplifier (op-amp) that uses a switched capacitor integrator has an advantage such as low power consumption and wide gain-bandwidth product. The power reduction is achieve by apply switching samples at the input and output capacitors. These capacitors can be otherwise would contribute in increase in power consumption. During the first phase of the sample the opamp compl...

This paper deals with the implementation of automatic power factor correction system using solid state switched capacitors and Arduino UNO controller. The main objectives are to reduce the line loss, to reduce reactive power flows on the line and to avoid switching surge overvoltage due to switching on/off the capacitors. This paper describes the design and simulation of power factor correction...

This paper presents a grid-connected system for renewable energy source (RES) applications. The proposed consists of modified switched-capacitor (SC) based multilevel inverter and DC-DC flyback converter. By using the converter voltages DC-link capacitors are adjusted to same values. SC-based has benefits like limited capacitor charging spike, reasonable size, power density, cost per output pow...

Thyristor controlled reactors provide controllable inductances in utility power lines and are increasingly used for static var control and flexible AC transmission. The size of a perturbation from a nominal periodic steady state can be measured by its incremental energy. This paper shows that incremental energy of a small perturbation increases when a thyristor switches on and decreases when a ...

The design of high gain, wide dynamic range op-amps for switched-capacitor circuits has become increasingly challenging with the migration of designs to scaled CMOS technologies. The reduced power supply voltages and the low intrinsic device gain in scaled technologies offset some of the benefits of the reduced device parasitics. An alternative comparator-based switched-capacitor circuit (CBSC)...
