Abstract (en)

[origin: EP1096834A2] Semiconductor components (Dij) are wired in multiple circuit groups, each group forming a subsidiary branch of current. A circuit is assigned to a constant power device (3) so that the sum of partial electrical currents flowing in subsidiary branches has a pre-determined constant value.
