DC-AC Converter

Our inverters, for traction or for auxiliary services, are normally built for 750Vdc input with one or mutiple controllable outputs. Used in reverse, as rectifiers connected to an asynchronous alternator, they allow to create a DC Link from a diesel genset, to supply a traction chain, also in combination with a hybrid battery system.
