Title (EN) VARIABLE VOLTAGE GENERATOR CIRCUIT, CAPACITOR AND METHOD
(FR) CIRCUIT GÉNÉRATEUR DE TENSION VARIABLE, CONDENSATEUR ET PROCÉDÉ
Abstract:
(EN) A variable voltage generator circuit is described for generating, from a substantially constant supply voltage VS, a variable high-voltage control voltage VC for a variable power capacitor (1) having a variable-permittivity dielectric. The control voltage generator circuit comprises a top-up circuit (10) for maintaining the voltage VCin on an input capacitor (12) at least at supply voltage VS, and a bidirectional DC-DC converter circuit (20) having a variable voltage conversion factor G controlled by control input signal (27). The bidirectional DC-DC converter (20) is arranged to convert voltage, at the voltage conversion factor G, between the input capacitor voltage VCin and the output voltage VC. When VC < G x VCin, the DC-DC converter circuit (20) uses charge stored in the input capacitor (12) to charge the capacitive load (1). When VC > G x VCin, the DC-DC converter circuit (20) uses charge stored in the load capacitance (1) to charge the input capacitor (12).
(FR) La présente invention concerne un circuit générateur de tension variable permettant de générer, à partir d'une tension d'alimentation sensiblement constante VS, une tension de commande haute tension variable VC pour un condensateur de puissance variable (1) ayant un diélectrique à permittivité variable. Le circuit générateur de tension de commande comprend un circuit d'appoint (10) qui permet de maintenir la tension VCin sur un condensateur d'entrée (12) au moins au niveau de la tension d'alimentation VS, et un circuit convertisseur CC-CC bidirectionnel (20) ayant un facteur de conversion de tension variable G commandé par un signal d'entrée de commande (27). Le convertisseur CC-CC bidirectionnel (20) est conçu pour convertir une tension, au niveau du facteur de conversion de tension G, entre la tension de condensateur d'entrée VCin et la tension de sortie VC. Lorsque VC < G x VCin, le circuit convertisseur CC-CC (20) utilise une charge stockée dans le condensateur d'entrée (12) pour charger la charge capacitive (1). Lorsque VC > G x VCin, le circuit convertisseur CC-CC (20) utilise une charge stockée dans la capacité de charge (1) pour charger le condensateur d'entrée (12).
