Abstract

The ballast includes three branch circuits connected in parallel and to lamps (L10 - L12) and a pair of oppositely wound transformers (Tr10,Tr11). The windings (10a,10b) of the transformer (Tr10) are connected in series with the lamp (L10) and the lamps (L11,L12) respectively. The windings (11a,11b) of the transformer (Tr11) are in series with lamp (L12) and the lamps (L10,L11) respectively.
