System thermal resistance testing

4.4.1

Heatsink thermal resistance

In order to test the thermal impedance of heatsink to ambient RthCA, the DC source is used to conduct the IPM

internal diodes, as shown in Figure 29. With the DC source voltage increasing, current through IPM IIPM and

voltage on IPM VIPM are monitored by current and voltage meter, the IPM case-temperature test point is

between IPM and heasink, as shown in Figure 29 below, the same as Tc point of inverter IGBT of the IPM

daasheet [1].

Thermal resistance between junction to ambient RthJA is divided into 2 parts as in the following formula: thermal

resistance between junction to case RthJC and thermal resistace between case to ambient RthCA.
