2.4.3 Power Converters DRAFT The power converters for the Super-FRS magnets are determined by the requirements of field homogeneity and stability. Experience is available from the operation of the present FRS facility. While for superconducting magnets the power converters need only provide the requested current, rather large power converters are needed for the power-consuming normal conducting, radiation resistant magnets in the 1 st stage of the Pre-Separator. For all types of power converters appropriate devices are available on the market and no special R&D work on this topic is foreseen. Although the magnets of the Super-FRS are operated in a DC mode the currents are required to be ramped up to the maximum current and down to zero within ≈120 s to allow for a fast change between different Bρ settings according to the experimental requirements. The basic parameters of the power converters are listed in section 2.4.3.7. The data on power cabling and cable terminals are included. Information on the number of cabinets and the floor space required are also given. Figure 2.4.76 shows the arrangement of the cabinets. The length of the power cables is derived from this arrangement. 2.4.3.1 General Aspects of Power Converters 2.4.3.1.1 Definition of Power Converters In this report the term Power Converter is used with the following meaning: • A Power Converter is a device with power part and control part for supplying current and voltage to a load in a controlled way. • The power part can be a single converter or a distributed system of power converters. 2.4.3.1.2 Interfaces of Power Converters There are interfaces for electrical power, for cooling, for protection and for control and display. Some basic considerations are listed: • Electrical power input: Small power converters are connected to the common 400 V three phase supply of the accelerator (not loaded by pulse power). Medium power converters are connected to the common 400 V three phase supply or to the 400 V three phase supply derived from the pulse loaded 20 kV system. All input contactors are part of the power converter. Power converters of high power have usually own 20 kV transformers (part of power converter) which are connected via 20 kV switch gear either to the common 20 kV supply system or to the pulse loaded 20 kV supply system. However the 20 kV switch gear is not part of the power converter, and the transformer has to be placed in a nearby transformer box of the building. The electrical supply for the control electronics of pulsed medium or high power converters is derived from the common supply system (not pulsed, 230V or 400V) via a miniature circuit breaker in the power converter. 69
