Static semi conductor electrical energy converter

摘要

The invention relates to a static semi-conductor electrical energy converter. The converter is of the type comprising a power stage 5 provided with at least one power transistor 7, and a control stage 1 furnishing a control signal SC appropriate for the conversion to be carried out; according to the invention, each transistor is a transistor having a voltage VCEX greater than its voltage VCEO and is associated with an intermediate stage 4 for treatment of the control signal SC. This stage 4 is adapted to drive the base of the said transistor to guarantee operation thereof over a voltage range extending from 0 to VCEX thus making it possible to take advantage of the improved voltage VCEX of the said transistor. The invention is applicable in particular in the case of inverters adapted to convert a continuous electric voltage into an alternating electric voltage.
