The invention relates to a system and method for controlling an electric generator connected to the electric supply grid during a voltage drop in the electric supply grid, the system including a bidirectional CA/CC/CA converter (2) connected between the generator (3) and the electric supply grid (4) and, in parallel to the converter next to the generator (2a), a rectifying means (5) connected in series between the generator (3) and the CC link (2b) of the bidirectional CA/CC/CA converter (2), thus providing an another way for the excess energy on the generator side to enter the CC link (2b).
