Title (EN) ELECTRICAL SYSTEM FOR STARTING UP AIRCRAFT ENGINES
(FR) SYSTEME ELECTRIQUE DE DEMARRAGE DES MOTEURS D'UN AERONEF.
Abstract:
(EN) The invention relates to an electrical system for starting up an engine (18, 20, 22), including: an AC/DC rectifier (12), supplied with power by an AC power network (14) in order to generate a first DC voltage Vdc; a DC/AC conversion module (12) for generating, on the basis of said first DC voltage Vdc, an AC voltage for starting up the engine, comprising n phase k inverters arrange in parallel (k>1) and generating power at least two times less than a maximum power Pmax that is required to start up the engine. The two power supply lines of each inverter are connected to an electronic protection device that receives the first DC voltage Vdc, and the n outputs of each inverter generate the AC voltage for starting up the engine by means of n inductors in series.
(FR) Système électrique de démarrage d'un moteur (18, 20, 22) comprenant : un redresseur AC/DC (12) alimenté par un réseau de puissance alternatif (14) pour délivrer une première tension continue Vdc, un module de conversion DC/AC (16) pour délivrer une tension alternative de démarrage du moteur à partir de ladite première tension continue Vdc, comportant k onduleurs à n phases disposés en parallèle (k>l) et délivrant une puissance au moins deux fois inférieur à une puissance maximale Pmax requise pour démarrer le moteur et les deux lignes d'alimentation de chacun des onduleurs sont reliées à un dispositif de protection électronique recevant la première tension continue Vdc et les n sorties de chacun des onduleurs délivrent la tension alternative de démarra e du moteur au travers de n inductances en série.
