Title (EN) BUCK-BOOST CONVERTER POWER SUPPLY WITH DRIVE CIRCUIT
(FR) ALIMENTATION ÉLECTRIQUE DE CONVERTISSEUR ABAISSEUR-ÉLÉVATEUR AVEC CIRCUIT D'ATTAQUE
Abstract:
(EN) A power supply (50) includes a first supply input node (38) and a second supply input node (40), a supply output node (42), first and second switch circuits (24, 28), a filter circuit (32), and a drive circuit (54). The first and second supply input nodes are respectively configured to receive first and second input voltages, and the supply output node is configured to provide an output voltage. The first switch circuit (24) has a first conduction node coupled to the first supply input node, a second conduction node, and a control node configured to receive a first control signal (S 1). The filter circuit has a first node (60) coupled to the second conduction node and has a second node. The second switch circuit (28) has a first conduction node coupled to the second node of the filter circuit, a second conduction node coupled to the second supply input node, and a control node. The drive circuit has an input node (58) coupled to one of the control node of the first switch circuit and the first node of the filter circuit, and has an output node (62) coupled to the control node of the second switch circuit.
(FR) Une alimentation électrique (50) comprend un premier nœud d'entrée d'alimentation (38) et un second nœud d'entrée d'alimentation (40), un nœud de sortie d'alimentation (42), un premier et un second circuit de commutation (24, 28), un circuit filtrant (32) et un circuit d'attaque (54). Les premier et second nœuds d'entrée d'alimentation sont respectivement configurés pour recevoir des première et seconde tensions d'entrée, et le nœud de sortie d'alimentation est configuré pour fournir une tension de sortie. Le premier circuit de commutation (24) comporte un premier nœud de conduction couplé au premier nœud d'entrée d'alimentation, un second nœud de conduction, et un nœud de commande configuré pour recevoir un premier signal de commande (S 1). Le circuit filtrant comporte un premier nœud (60) couplé au second nœud de conduction et un second nœud. Le second circuit de commutation (28) comporte un premier nœud de conduction couplé au second nœud du circuit filtrant, un second nœud de conduction couplé au second nœud d'entrée d'alimentation, et un nœud de commande. Le circuit d'attaque comporte un nœud d'entrée (58) couplé au nœud de commande du premier circuit de commutation ou au premier nœud du circuit filtrant, et un nœud de sortie (62) couplé au nœud de commande du second circuit de commutation.
