Pulsed power converter for SIS18 injector quadrupole magnets

Broadly, the power converter can be divided in two parts: 1. Power part It is supplied by a 400V, 3-phase Common supply system, C1 (Sec. 5.1 of [2]) 2. Control part It is supplied by a 400V, 3-phase Common supply system, C1 (Sec. 5.1 of [2]). Table 4-1 gives the technical parameters for the power part. The design principles for the main components and functionalities of the power part can be found in Sec. 3 and 8.5 of [2]. From the standardization point of view, it is mandatory for the power converters to be compatible with the ACU systems and the DCCTs, which will be provided by the Company. The ACU system has to be integrated in the control part of the power converter. Further details can be found in Sec. 8.3 and 8.4 of [2]. One high precision DCCT (per power converter) is needed and it must be installed at the output of each power converter. Contrary to Sec. 6.3 of [2], the output from the power converter shall be supplied to the load through one four-core multi-conductor cable. Selection of the cable will be governed by the type of the power converter (Table 4-1). The cable length is determined by the physical distance between the power converter and the magnet (Figure 1) and the routing of the cable trays.
