DUAL ACTIVE BRIDGE CONVERTER AND METHOD TO CONTROL SUCH A CONVERTER.

摘要

The invention relates to a double bridge converter comprising:- a transformer (3);- A first switching bridge (20) AC / AC type connected to the primary winding of the transformer which comprises at least two switching arms;A second AC / DC switching bridge (21) connected to the secondary winding of the transformer (3);- A resonant circuit connected to the first switching bridge and the primary winding of the transformer and having a resonance capacitor (Cr) in series with an inductor (Lr);- Each switching arm of the first switching bridge comprises at least a first bidirectional transistor (TH1, TH2) with two gate electrodes and a second transistor (TL1, TL2) bidirectional two gate electrodes connected in series.
