[en] With the HV-power supply the following nominal voltages and currents can be obtained: 8*35 kV/40 A or 8*70 kV/20 A or 4*70 kV/40 A or 4*140 kV/20 A or 2*105 kV/40 A. The nominal current can be taken for 10 sec with a repetition rate of 2 minutes. The above values are obtained by a series-parallel arrangement of eight twelve pulse double modules, each 2*35 kV/20 A. The voltage is regulated by a thyristor star point controller in the primary of the high voltage transformer. Every circuit was tested with a water resistor as a dummy load. The voltage is continuously adjustable from 5% to 100%. The static regulation is better than 0.1%. The dynamic voltage drop from no load to full load is less 5%. The ripple with full current is less than 0.1%
