Abstract

Un dispositif de commutation bidirectionnel comprend un montage en pont de diodes et un commutateur à semi-conducteurs. Le montage en pont de diodes est configuré pour commander une direction de flux de courant à travers le dispositif de commutation bidirectionnel, en réponse à un courant alternatif appliqué au dispositif de commutation bidirectionnel.
