Abstract
(EN)
A power supply circuit and device, comprising: the circuit comprises multiple channels, and at least one channel in the multiple channels comprises a first switch tube (M1'), a second switch tube (M2'), a third switch tube (M1), a fourth switch tube (M2), a first capacitor (C1'), and a second capacitor (C1), wherein one end of the first capacitor is connected to one end of the second capacitor; the other end of the first capacitor is separately connected to a first pole of the first switch tube and a first pole of the second switch tube; a second pole of the first switch tube is connected to a second pole of the third switch tube; a second pole of the second switch tube is connected to a second pole of the fourth switch tube; a third pole of the first switch tube is connected to an output node; and a third pole of the second switch tube is grounded. The present solution balances a charging charge of the second capacitor by means of an ideal charge storage quantity of the first capacitor, so that the stability of a circuit system is improved, and thus the dynamic property of the circuit system is improved.

Un deuxième pôle du premier tube de commutation est connecté à un deuxième pôle du troisième tube de commutation. Un deuxième pôle du deuxième tube de commutation est connecté à un deuxième pôle du quatrième tube de commutation. Un troisième pôle du premier tube de commutation est connecté à un nœud de sortie. Un troisième pôle du deuxième tube de commutation est mis à la terre. La présente solution équilibre une charge du second condensateur au moyen d'une quantité de stockage de charge idéale du premier condensateur, de telle sorte que la stabilité d'un système de circuit est renforcée et ainsi, la propriété dynamique du système de circuit est améliorée.
