Patent ID: 6867570

Claim:
A circuit arrangement for static generation of a variable electrical power for a load, in which the load is connected, by using anti-parallel connected static switches, to the secondary winding of a transformer whose primary side is connected to an alternating voltage source, in which the secondary winding of the transformer (T) provides at least two control windings serving as partial windings (W 1 , W 2 ), in which each partial winding is connected to a bridge circuit (B 1 , B 2 ) which comprises two anti-parallel connected static switches (BSS 1 . . . 4 ) in each bridge branch, and in which the bridge circuits (B 1 , B 2 ) are arranged in series with respect to each other and are arranged in parallel with respect to the load (C, D), wherein the load comprises a parallel circuit of two reactive-power loads in form of a inductor (D) and a capacitor (C), and wherein the at least two windings (W 1 , W 2 ; W 11 , W 12 ) each of the secondary side of the transformer with the associated bridge circuits (B 1 , B 2 ; B 11 , B 12 ) are assigned to the inductor as well as to the capacitor, respectively.
