Title (EN) WIDE RANGE POWER SUPPLY
(FR) ALIMENTATION FOURNISSANT UNE GAMME DE TENSION ETENDUE
Abstract:
(EN) A wide range power supply (500) capable of delivering 20V to 5000V is provided. The power supply (500) uses switch mode technology to achieve high overall operating efficiency and is capable of operating from no load to foil load without loss of regulation. The power supply (500) operates directly from the utility supply (502) of 110V/220V and 50Hz/60Hz. The power supply (500) includes an input rectifier stage (505), a buck converter stage (510), a quasi-resonant inverter stage (515), and a voltage multiplier stage (525). The stages are connected in series to achieve the large output voltage range. High precision is obtained from a use of a digital feedback loop (535 and 550) in connection with an analog feedback loop (555).
(FR) L'invention concerne une alimentation fournissant une gamme de tension étendue allant de 20V à 5000V. Cette alimentation utilise une technologie de mode de commutation pour obtenir un rendement de fonctionnement global élevé et est capable de passer d'une tension à vide à une tension pleine charge sans perte de régulation. Cette alimentation, selon des modes de réalisation de la présente invention, peut être branchée directement au secteur (110/220 V et 50/60 Hz, par exemple). Dans un mode de réalisation, l'étage de conversion comprend les éléments suivants : un circuit redresseur d'entrée ; un circuit convertisseur abaisseur de tension ; un circuit inverseur quasi-résonant ; et un circuit multiplicateur de tension. Ces éléments sont montés en série pour obtenir une gamme de tension de sortie étendue. L'utilisation d'une boucle de rétroaction numérique et, éventuellement, d'une boucle de rétroaction analogique, permet d'obtenir une grande précision.
