<p>The invention relates to DC/AC current convertors. It relates to a convertor in which a circuit (11) transmits an input DC current at a carrier frequency (FP) and modulated at a chopping frequency (FD), to a transformer (12). An output circuit (13) reconstructs an output wave form. According to the invention, the output circuit (13) comprises controlled bi-directional circuit breakers, with the result that the convertor is reversible and can also be used as a rectifier. Application to the construction of uninterruptory power supplies. <IMAGE></p> |
