Front end current distortion of rectifier converter leads to low power factor, high THD, distribution system losses, neutral harmonic currents, over rated power equipments in a power system. In addition, the presence of harmonics in line currents may lead current distortion, create additional heating and over voltage problem, loading and losses in the utility distribution systems. The aim of th...

A linear, second-order filter driven by randomly polarized pulses is shown to generate a waveform that is chaotic under time reversal. That is, the filter output exhibits determinism and a positive Lyapunov exponent when viewed backward in time. The filter is demonstrated experimentally using a passive electronic circuit, and the resulting waveform exhibits a Lorenz-like butterfly structure. Th...

Algorithms working in mode space instead of directly matching the received complex sound pressure were developed to improve computational efficiency and robustness, but these algorithms may be inconvenient apply practice because manual operations are often inevitable when performing modal filtering. Based on a phase-matched filter, an imperfect scheme named phase based matched impulse response ...

The recent trends show the interconnection of PV system with electric grid. With this configuration issue harmonics comes into existence. mounting figure power-electronic instruments has formed considerable impression on power-quality supply. Harmonics deformations have conventionally been handled amid application passive-LC filters. Active Filter emerged as a good substitute for passive filter...

In [1] a prospective current-mode ARC filter implementation based on a wave description principle has been introduced. This idea can be easily modified to obtain sampled-data SI filter structure, as shown in [2]. Similarly to the "conventional" digital wave filters, the analog implementation is based on the description of the passive LC prototype ladder structure branches using scattering matri...

Abstract – The components of harmonics are integral multiple of the fundamental component and the components of inter-harmonics are are non integral multiple of the fundamental component. AC-DC-AC conversion systems used in variable speed drive are sources of inter-harmonics. There are several reasons for inter-harmonic generation in variable speed drives. In this paper, the generation of inter...
