4.3. Thermal specifications
Thermal performance of Everest CORE is specified as function of the
temperature measured in its aluminium
case
, the
DC bus voltage
and the
PWM commutation frequency
. This 3 parameters could ultimately determine
the maximum continuous current the Everest CORE can output, provided that an
active derating
algorithm will be
continuously protecting it from thermal over-stress. Notice that PWM commutation frequency cannot be changed
dynamically, but pre-selected to match the application needs: most probably 10 kHz will be selected for
highest current at a given temperature (be aware that selecting this frequency may cause audible noise), but 100
kHz will be preferred to control a low inductance motor.
The following figure show the maximum phase current at different case temperatures and DC bus voltages.
Here
current is expressed in RMS
. To obtain the equivalent current in amplitude just multiply it by
√
2 .
To ensure a proper performance of Everest CORE, the
case temperature must be held always below 85 ºC (T
c-
max
=
85 ºC).
