CA 2113031

An inverter device is connected to output ends of a full-wave rectifier for full-wave recification of an AC input voltage from an AC power source, and includes an inductance component in a loop formed with a load circuit including an LC resonance series for charging a DC power-source capacitor through one of a pair of switching elements, whereby a high input power factor is maintained while reducing any distortion of input current, and a control of the switching elements which function to restrain any rush current can be simplified.

Dispositif onduleur branché aux extrémités de sortie d'un redresseur pleine-onde afin d'assurer le redressement pleine-onde d'une tension d'entrée c.a. provenant d'une source de courant c.a. Comprend une inductance montée dans une boucle formée avec un circuit de charge comprenant un circuit résonnant série LC afin de charger un condensateur de source d'alimentation c.c. par l'intermédiaire d'une paire d'éléments de commutation, ce qui permet de maintenir un facteur élevé de puissance d'entrée tout en réduisant la distorsion du courant d'entrée, et de simplifier la commande des éléments de commutation servant à restreindre le courant d'appel.
