Title (EN) REDUCING CURRENT HARMONICS AT LIGHT LOADS
(FR) RÉDUCTION DES HARMONIQUES DE COURANT À CHARGES LÉGÈRES
Abstract: front page image
(EN)Reducing current harmonics at light loads is disclosed. In an example, a method includes increasing output voltage of a boost converter to reach a higher potential in a low power mode. After reaching the higher potential, the method includes dropping a set point for the output voltage.
(FR)L'invention concerne la réduction des harmoniques de courant à des charges légères. Dans un exemple, un procédé comprend les étapes consistant à augmenter la tension de sortie d'un convertisseur élévateur pour atteindre un potentiel plus élevé dans un mode de faible puissance. Après avoir atteint le potentiel plus élevé, le procédé comprend les étapes consistant à réduire un point de consigne pour la tension de sortie.
