Title
(EN) MULTI-RESONANT INVERTER
(FR) INVERSEUR MULTI-RESONNANT
Abstract
(EN)
A multi-resonant circuit has a series-resonant circuit (118) coupled to the input of an inverter (120). The output of the inverter is coupled to a parallel resonant circuit (108, 152). The output of the parallel resonant circuit energizes a load (142, 140), which could be gas discharge lamps. The operating frequency of the inverter (120) is between the resonant frequency of the series-resonant circuit (118) and the resonant frequency fo the parallel resonant circuit (108, 152).

Circuit multi-résonant comportant un circuit de résonance série (118) couplé à l'entrée d'un inverseur (120). La sortie de l'inverseur est couplée à un circuit résonnant parallèle (108, 152). La sortie du circuit résonnant parallèle active une charge (142, 140), pouvant être des lampes à décharge de gaz. La fréquence de fonctionnement de l'inverseur (120) se situe entre la fréquence de résonance du circuit résonnant série (118) et la fréquence de résonance du circuit résonnant parallèle (108, 152).
