Design Method Based on Normalized Functions for a Toroidal Inductor Applied to Power-Quality Evaluation

Abstract

<p class="MsoNormal" style="text-align:justify;"> <span lang="EN-US">The design method for a low-cost toroidal inductor is proposed as an alternative to power-quality evaluation. The method is based on well-known tools by the engineers in which is presented the relationships that exist between equivalent circuit and transfer function of a toroidal inductor. The proposed design method has been explained with normalized functions based on physical parameters of a toroidal inductor. This work present</span><span lang="EN-US">s</span><span lang="EN-US"> the main arguments of the suggested methodology and as demonstration of the design method as function of normalized parameters, is developed a current-signal sensor which has been validated in the laboratory by the EN-5<st1:chsdate year="160" month="2" day="2" islunardate="False" isrocdate="False" w:st="on">0160-2-2</st1:chsdate> standard to evaluate the power quality in home use loads.</span><span lang="EN-US"><o:p></o:p></span> </p

Reliable Energy Strategy Based on Incandescent Lighting

“…As comparison, the single harmonic distortion (SHD) values for a switching-mode supply are presented in Table 2 to demonstrate that the controlled tungsten-filament by the IAC is more reliable. Both third and seventh harmonic are lower for the IAC circuit than those registered by the switching-mode supply [15]. As a result, the overcurrent in the neutral line, resonant over voltages and copper area oversize are reduced even at 90 α = , because production of distorted-current with single SHD < 50% do not produce hazard.…”
