Title
(EN) CAPACITIVELY COUPLED CELL BALANCER WITH A COMMON AC BUS
(FR) COMPENSATEUR DE CELLULES EN COUPLAGE CAPACITIF AVEC UN BUS DE COURANT ALTERNATIF COMMUN
Abstract
(EN)
This invention concerns a capacitively coupled cell balancer with a common AC bus. It comprises either a half or full bridge connected to each cell of a set of N cells, which are either floating or connected in series. The midpoints of each half bridge and the full bridges are coupled through coupling capacitors to a common AC bus.
(FR)
La présente invention concerne un compensateur de cellules en couplage capacitif avec un bus CA commun. Il comporte soit un demi-pont soit un pont complet connecté à chaque cellule d'un ensemble de N cellules, qui sont soit flottantes soit connectées en série. Les points intermédiaires de chaque demi-pont et des ponts complets sont couplés à travers des condensateurs de couplage à un bus CA commun.
