4.1 Introduction
The following chapter describes in short the main components/blocks of the SYSTEM 9100.
An overview of the SYSTEM 9100 architecture can be found on next page.
Furthermore an interface specification i.e. an overview of the possible connections will be
listed with description of every single pin and its use.
Technical description
The power supply modular system is mounted in a 19” rack. The dimension of the rack is 3U
high and 600mm deep.
This allows for quick replacement of all modules and print circuit boards in Magnet Power
Supply. Thus this reduces service-time and total down time.
The System 9100 is a full bridge phase modulated, zero voltage-switching converter, which
offers several benefits compared with traditional hard-switching technology.
Figures below are block diagrams of the SYSTEM 9100 unipolar and bipolar type. There are
11 blocks and each block will be described in short.
-EMI filter.
-Diode module
-Soft start module
-AC input filter module.
-Output modules (1 to 4 modules depending of max output current)
-Aux power supply, PCB.
-I-loop, CPU control, interlock, PCB.
-DCCT transducer.
-Display module.
-Local control M-panel.
-Bipolar output stage (Bipolar only)
