dc.description.abstract The derivation of the harmonic currents produced by static power converters requires accurate information of the AC voltage waveforms at the converter terminals, converter configuration, type of control, AC system impedance and DC circuit parameters. The main sources of harmonic current are at present the phase angle controlled rectifiers and inverters. Some experimental tests have been done using a semicontrolled three-phase bridge rectifier from the laboratory of Dipartimento di Ingegneria Elettrica Industriale, Politecnico di Torino, Italy. The parameters which could be varied were the load inductance and capacitance, and the firing angle. en_US
dc.description.abstract Analiza armonicelor de curent produse de convertoarele de putere statice implică obţinerea de informaţii exacte referitoare la forma de undă a tensiunii la bornele convertorului, configuraţia acestuia, tipul de control, impedanţa sistemului şi parametrii circuitului de curent continuu. În prezent, principala sursă de armonici de curent o reprezintă redresoarele controlate şi invertoarele. O serie de teste experimentale au fost realizate folosind un redresor trifazat semicontrolat în laboratoarele din cadrul Dipartimento di Ingegneria Elettrica Industriale, Politecnico di Torino, Italia. Ca parametri variabili s-au considerat inductanţa şi capacitatea sarcinii, precum şi unghiul de comandă. ro

Au présent les redresseurs contrôlés et l’onduleur sont la source principale des harmoniques de courant. On a réalisé de testes utilisant un redresseur triphasé semi-contrôlé au Laboratoire de Dipartimento di Ingegneria Elettrica Industriale, Politecnico di Torino, Italie. Les paramètres variables sont considérés l’inductance et la capacité de la charge et l’angle de commande. fr
dc.description.abstract Анализ токовых гармоник производимых статическими силовыми выпрямителями позволяет получение точных информаций касающиеся формы волны напряжения в контактах выпрямителя, его конфигурация, тип контроля, импеданс системы и параметры цепи постоянного тока. А настоящее время основным источником токовых гармоник являются контролируемые выпрямители и инверторы. Были выполнены серия тестов на полуконтролируемый трёхфазный выпрямитель в лаборатории из Dipartimento di Ingegneria Elettrica Industriale, Politecnico di Torino. ru
