description	The invention relates to a DC/AC-converter for supply of TL-lamps, comprising a bridge circuit of switch elements, a control circuit for control of the switch elements, so that subsequently a ground voltage, a positive voltage, a ground voltage, a negative voltage and a ground voltage is obtained on the first output, wherein the TL-lamp is to be connected between the first an the second output. This arrangement of the switching elements avoids periods of time during which the lamp voltage is kept floating so that flickering of the lamp is avoided. La présente invention a trait à un convertisseur CC-CA destiné à l'alimentation de lampes TL, comportant un circuit en pont d'éléments commutateurs, un circuit de commande pour la commande des éléments commutateurs, de manière à obtenir ultérieurement une tension de masse, une tension positive, une tension négative et une tension de masse sur la première entrée, la lampe TL étant destinée à être connectée entre la première et la deuxième entrées. Cet agencement des éléments commutateurs élimine les intervalles de temps durant lesquels la tension de la lampe est maintenue flottante de manière à éviter une oscillation de la lampe.
