“…This is the case of engine sound quality. Some researchers prefer the use of loudness, roughness and sharpness indicators in car applications (Redel-Macias et al, 2012, Lara et al, 2015. Loudness provides a subjective measure of the sound energy content and its unit of measurement is sone.…”

A Sociedade Portuguesa de Segurança e Higiene Ocupacionais realiza, em 26 e 27 de Março de 2018, a 14ª edição do Colóquio Internacional de Segurança e Higiene Ocupacionais - SHO 2018. Tal como nos doze últimos anos, o evento tem lugar no Auditório Nobre da Escola de Engenharia da Universidade do Minho, em Guimarães. A edição de 2018 abrange as temáticas da Ergonomia e do Ambiente Físico, dos Riscos Químicos e Biológicos, da Segurança contra Incêndio e da Gestão da Prevenção, que são objeto de sessões plenárias, decorrendo ainda várias sessões paralelas de comunicações livres nas 26 áreas temáticas previstas para o evento, bem como várias sessões com apresentação de posters.

“…The use of power inverters is very widely-used for a multitude of applications [1] [2], among them, feeding electric motors [3] [4] and most notably in those which, due to their construction characteristics [5], were designed to work within a reduced speed range, as in the case of the asynchronous induction motor, since the use of inverters allows some operating characteristics of these machines to be modified, for example, their speed [6] [7]. The inverter transforms a DC voltage, which can come from the rectification of the grid voltage, into a voltage signal modulated in frequency whose waveform will depend on the pulse-generating signals that give rise to the output voltage.…”

This work presents a new interactive tool for the study of the quality of power supply signals generated by an inverter. The tool has interactive elements to model and implement PWM techniques in a power inverter, it allows to modify any parameter of the PWM technique during the control of the inverter, being this a great advantage to make a lot of tests in a short time. In addition, the tool allows to design offline and simulate the behavior of the load that will feed the inverter. For the realization of the tool was used the graphic programming language Labview, for the control an Atmega328-PU microcontroller and an inverter Semikron-Semitech. A total of 1438 tests were carried out on a dhalander motor in 72 hours with two PWM techniques modelled with the tool, which made it possible to study the feed signal and the motor behaviour in the whole range of possible values that the parameters defining each PWM technique could take. The tool provides a great help to the experimental study of the quality of the power supply signals generated with an inverter for the power supply signal.

“…Therefore, the noise increases if the motor is fed by a non-sinusoidal signal, for instance, when a power inverter is used to generate the feed signal, using Pulse Width Modulation (PWM) techniques. This sort of technique is widely used to control the operation of the induction machine, emitting a higher noise [1,2].…”
