This paper presents a discussion of the compensation of non-periodic currents such as those associated with arc furnaces. Based on the compensation objectives for different types of load waveforms, the energy storage requirements of the compensator are also presented. Further, basic concepts required in the definition of nonactive current are presented and illustrated by simulations for a varie...

Using a simple and well-known voltage-to-current transformation, current-mode active RC filters that are amenable to IC realization can be derived from their voltage-based counterparts. Using this transformation, a classification of current-based single-amplifier biquads is introduced which is derived from a similar voltage-based classification. This classification is exhaustive in that it incl...

Characteristics of tunable wavelength filters based on a-SiC:H multilayered stacked cells are studied both theoretically and experimentally. Results show that the light-activated photonic device combines the demultiplexing operation with the simultaneous photodetection and self amplification of an optical signal. The sensor is a bias wavelength currentcontrolled device that make use of changes ...

This paper is devoted to the implementation of a parallel active power filter prototype in a nonideal power grid. The control algorithm is described and realized. Simulation and experimental results proved the theoretical prediction. Analytical conditions of the usable implementation are shown. Some guidelines are presented in the conclusion.

In previous works a technique for doing single fault diagnosis in linear analog circuits was developed. Under certain conditions, one of them being exact circuit parameters, it was shown that only two measurements taken on two selected circuit nodes, at a single frequency, were needed to detect and diagnose any parametric fault. In this paper, the practical value of the technique is evaluated b...

This paper presents the comparative evaluation of the performance of three state-of-the-art current control techniques for active filters. The linear rotating frame current controller, the fixed-frequency hysteresis controller, and the digital deadbeat controller are considered. The main control innovations, determined by industrial applications, are presented, suitable criteria for the compari...
