Title
(EN) POWER SUPPLY WITH INTEGRAL FILTER AND COOLING DEVICE
(FR) ALIMENTATION EN COURANT A FILTRE ET A DISPOSITIF DE REFROIDISSEMENT SOLIDAIRES
Abstract
(EN)
A power supply in accordance with the present invention includes a chassis (26) associated with the power supply; a voltage source (12) providing an output voltage varying at a fundamental frequency and having a noise component changing as a function of time at a frequency above the fundamental frequency; a filter (41) including an inductance (44) in series with the voltage source for attenuating the noise component and outputting the fundamental frequency; and a cooling apparatus (42) thermally and capacitively coupled to the inductor for conducting heat from the inductor and shunting the noise component to the chassis.
(FR)
Une alimentation en courant selon l'invention comprend un châssis (26) associé à ladite alimentation en courant; une source de tension (12) produisant une tension de sortie variant à une fréquence fondamentale, et présentant une composante de bruit changeant en fonction du temps à une fréquence supérieure à la fréquence fondamentale; un filtre (41) comprenant une inductance (44) en série avec la source de tension, destiné à atténuer la composante de bruit et à produire la fréquence fondamentale; ainsi qu'un appareil de refroidissement (42) couplé thermiquement et de manière capacitive à l'inducteur afin de conduire la chaleur provenant de ce dernier et d'envoyer en dérivation la composante de bruit vers ledit châssis.
