(57) Abstract:
(EN): A voltage equalization circuit, a voltage equalization method and a device. The voltage equalization circuit comprises: a driver (11), a variable resistance unit (12) and a calculation unit (13). The driver (11) is connected to the variable resistance unit (12) and the calculation unit (13), and the variable resistance unit (12) is also connected to the calculation unit (13). The driver (11) is configured to acquire the voltage across the calculation unit (13), and adjust the resistance of the variable resistance unit (12) according to the voltage across the calculation unit (13), so that the voltage across the calculation unit (13) is within a preset voltage range. By means of said method and device, the reliability of a circuit is improved.
(FR): L'invention concerne un circuit et un procédé d'égalisation de tension, et un dispositif. Le circuit d'égalisation de tension comprend : un circuit d'attaque (11), une unité de résistance variable (12) et une unité de calcul (13). Le circuit d'attaque (11) est connecté à l'unité de résistance variable (12) et à l'unité de calcul (13), et l'unité de résistance variable (12) est également connectée à l'unité de calcul (13). Le circuit d'attaque (11) est configuré pour acquérir la tension à travers l'unité de calcul (13), et régler la résistance de l'unité de résistance variable (12) en fonction de la tension à travers l'unité de calcul (13), de telle sorte que la tension à travers l'unité de calcul (13) se situe dans une plage de tension prédéfinie. Au moyen desdits procédé et dispositif, la fiabilité d'un circuit est améliorée.
