MA040E12_EVAL – Isolate Gate Driver Power Supply
and Logic Interface for MIPAQ
3.1.3
For some applications it is necessary to avoid the accidental operation of equipment during the
standby. One way to achieve this is to cut off the power supply of the top IGBT drivers by the safety
relay contact P1 Figure 9. The jumper J1 is set as default. Jumper J1 needs to be removed if this
functionality is used. The status of P1 can be observed over the contact P2 for an external monitoring.
P2 is available on pin 215 and 216 of connector X2
The relay of K1 can be activated by 15V / 60mA using the connector X5.
3.1.4
The output power and output voltage of the MA040E12 board as shown in Figures 10 and 13 are
varying as a function of the switching frequency of the IGBT at 125°C MIPAQ
temperature.
The variation of the negative output voltage shown on Figure 10 has no influence on the switching
behavior of the MIPAQ
