Evaluation Kit EASYKIT AUX DRIVES (FS50R07W1E3_B11A)
2 Quick Start Guide
Before operating this Evaluation Kit two steps are necessary:
1. Mount system on a cooling plate
2. Connect aux supply, HV supply and a 3phase AC motor (or alternative load)
3. Motor starts running automatically per default (see chapter 4 for CAN control modes)
Please read the entire application note carefully in order to prevent accidents and damage on the
Evaluation Kit.
2.1 Mount System on a Cooling Plate
The power module can be attached directly on a cooling plate after applying a thermal grease of 50 um
thickness (e.g. Fischer WLP). Detailed information on the mounting of the Easy Automotive Module can be
found in [2].
Figure 2 Mounting for quick start with the Evaluation Kit. Standard thermal grease is applied between
module and cooler. The module is fixed with screws via the module integrated clamps. See
Application Note [2] for recommended mounting instructions.
The cooler design depends on the specific requirements of the target system. The highest performance and
power density can be achieved with water cooling systems. Nevertheless, forced air cooling is typically
easier for first tests in the high voltage lab. An example of a forced air cooler was designed, where the DCL-
capacitor was placed on the bottom of the PCB to achieve a compact system design (see Figure 3). The
drawings for the sample air cooler can be taken from Figure 4.
Measurements with the cooler prototype Assmann WSW: ASS_1060_HSrev01 and FAN: AFB0612VHC
running at 15 V showed an Rth (heatsink to ambient) of approximately 0.4 K/W.
