Hardware Description

Figure 2-13 TTOFF: Principle of Operation

Two Level Turn-On (TTON)

In order to increase EM compatibility and the efficiency of the whole system, the 1EDI2002AS supports the Two

Level Turn-On functionality (TTON). The TTON function consists in switching the IGBT on in three steps in such

a way that:

1. The IGBT gate voltage is first increased until a specific (and programmable) voltage is reached by the TON

signal.

2. TON (and TOFF) voltage is stabilized at this level. The IGBT Gate voltage forms thus a plateau.

3. Finally, the switch-on sequence is resumed up to the maximum output voltage.

The TTON feature needs to be activated by configuring the delay with bit field SCFG2.TTOND.
