Title (EN) AN AC-DC POWER SUPPLY
(FR) CONVERTISSEUR DE COURANT ALTERNATIF EN COURANT CONTINU
Abstract:
(EN) This invention provides an AC-DC power supply for receiving a three phase mains supply and outputting a transform DC supply. The power supply unit has a rectifier circuit providing an output to a controlled three phase inverted circuit to generate a pseudo-AC three phase output of higher frequency than the AC supplied to the rectifier circuit. A three phase transformer is provided to receive the pseudo-AC three phase output and transform the output and provides us to a three phase rectifier circuit to generate the toutput DC supply. The inverter circuit may provide a three leg bridge structure with each leg having a controlled switching device one of which is used to provide a phase reference. The switching devices of the other two legs may control the relative phase shift on each leg to reduce the phase shift relative to the phase reference on one leg and increase the phase shift relative to the phase reference on the other leg. This is used to control the output voltage level of the inverter circuit. The entire AC-DC power supply may be linked to a gas generator for the electrolysis of water to liberate hydrogen and oxygen.
(FR) L'invention concerne un convertisseur de courant alternatif en courant continu, alimenté avec un courant triphasé et fournissant un courant continu. Le convertisseur a un circuit redresseur alimentant un circuit onduleur triphasé asservi, fournissant un courant pseudoalternatif triphasé d'une fréquence supérieure à celle du courant alternatif fourni au circuit redresseur. Un transformateur pour courant triphasé reçoit le courant pseudoalternatif triphasé et alimente un circuit redresseur pour courant triphasé, pour fournir une sortie de courant continu. Le circuit onduleur peut constituer une structure à trois branches, dont chacune a un dispositif commutateur asservi dont un est utilisé pour fournir la référence de phase. Un dispositif commutateur des deux autres branches peut réguler le déphasage relatif sur chaque branche pour diminuer le déphasage par rapport à la référence de phase sur une branche et augmenter le déphasage par rapport à la référence de phase sur l'autre branche. Ceci est utilisé pour réguler le niveau de la tension de sortie du circuit onduleur. Le convertisseur de courant alternatif en courant continu peut être associé à un appareil d'électrolyse de l'eau, générant de l'hydrogène et de l'oxygène.
