Converter “safe” protection chain principle
Each RegFGC3 card can act on the protection chain of the converter. The protection chain acts on SKMCB pins 10,11 which controls the undervoltage coil of the MCB and interrupts the circuit immediately. The state machine for example has several inputs that act on this chain;

DSP HEX switches
The HEX1 and HEX2 switches are decided based on the following rule that combines the converter information and switching frequency information into one Hex code: 2^(TypeNum) x (Fsw,H-bridge + Fsw,boost) For example for SIRIUS S with type number=10: 2^(10) x (6500+13000)=2.00E+7 (rounded up) Hex 2 is defined by the decade (=7), Hex 1 by the
