A novel current injection network for low-harmonic rectifiers that apply the third harmonic current injection is proposed in this letter. The current injection network requires one inductor, two capacitors, and one 1 : 1 transformer with voltampere rating of only 0.16% of the input power. The transformer is introduced to provide complete rejection of harmonic components of the injected currents...

A new topology for translinear filters in CMOS IC technology is presented. This translinear filter is based on the exponential relation of passive PN-diodes in CMOS technology while the CMOS transistors only provide gain. From simulations, it is demonstrated that this topology leads to an improvement in high-frequency performance. Cut-off frequencies higher than 200 MHz with Total Harmonic Dist...

This work describesasteady state analysis of a building with a 6 kW photovoltaic system interconnected to the grid. Thebuilding is“Centro de Investigación de los Programas de Ingeniería – CIPI” at Universidad de Bogotá Jorge Tadeo Lozano, in Bogotá, Colombia. The photovoltaic system is installed on the building’s roof and it has been operating properly since the month of January 2015. Steady st...

Attempts to formulatemathematically precise definitions of basic concepts such as causality, randomness and probability have a long history. The concept of hierarchical definability that is outlined in the following suggests that such definitions may not exist. Furthermore, it suggests that existing definitions of many basic concepts, among them those of linearity stability, statistical indepen...

In this paper, we consider a designed and implemented phase-cutting dimmer. In fact, the dimmer is closed loop and a microcontroller calculates and then regulates the firing delay angles of each channel. Depending on the firing angle, the harmonic distortion in the input current will not comply with international standards, such as IEC 61000-3-2 (class C equipments). For solving this problem, e...

Introduction The power quality of distribution systems has a drastic effect on power regulation and consumption. Johan Lundquist of the Chalmers University of Technology in Goteberg, Sweden put it best, stating “The phrase ‘power quality’ has been widely used during the last decade and includes all aspects of events in the system that deviates from normal operation.” This has been especially tr...

Standard production test techniques for ADC require an ATE with an arbitrary waveform generator (AWG) with a resolution at least 2 bits higher than the ADC under test resolution. This requirement is a real issue for the new high-performance ADCs. This paper proposes a test solution that relaxes this constraint. The technique allows the test of ADC harmonic distortions using only low-cost ATE. T...

This paper presents the comparative study of three phase twenty five level diode clamped and cascaded H-bridge multilevel inverters. The comparison is made in respect of requirement of devices, quality of output voltage and reduction of total harmonic distortion at the multilevel inverter terminals. In this work multicarrier sinusoidal pulse modulation control methods of Phase disposition (PD-P...
