Static semi-conductor electrical energy converter assembly

摘要

A static conversion assembly comprises a serial connection of n apparatus each formed by the association of two converters ( DELTA ) of the type described in U.S. Pat. No. 4,330,819. Each control stage of a given apparatus (..) is adapted to furnish opposite control signals to the two controlled blocking static interrupters of each apparatus ( DELTA ). In addition, the assembly of control stages of the apparatus ( DELTA ) is driven by a centralized control unit (56) which provides a delay in the control signals of an apparatus ( DELTA ) with respect to the control signals applied to a preceeding apparatus in the serial arrangement thereof. In addition, a voltage distribution stage (51) is connected to the apparatus (..) in order to divide the applied voltage and apply only a fraction thereof to each interrupter.
