SCR/SM Topology: for
Dipole Power Converter
The dipole magnets will be connected in series and powered from a common power
converter. Because of the large power it is connected to the 20kV level .

The system consist of:
•
a twelve pulse SCR with controlled
freewheeling thyristor. This
component handles the large power.
•
an parallel active filter PE. This
component takes care of the current
ripple and current dynamics.
•
a mechanical changeover switch to
reverse the current polarity.

Slow-pulsed Power Converter for Injection Septum Magnets
• pulse power has to be taken from the grid
• energy recovery
• 2 existing transformers of 670kVA each are available and can be reused (after
upgrade of SIS100 prototype test facility in Dec. 2012)

1 In-kind Contribution
ACU and DCCT: German
From the standardization point of view, all the power converters in FAIR
has to be equipped with:
• the Adaptive Control Unit, ACU, a digital control unit
• the Direct-Current Current Transformer, DCCT, a high precision
load current measuring device
