= +

Thus we get the following formula:

=∆. = −×

According to the test set-up, the test results are shown in Figure 30 below. The IPM case temperature is

detected for about one hour, until the temperature is stable.

Therefore, the final case-to-ambient resistance value is roughly:

=2.4℃/

Please note that thermal resistance is calculated with a fan voltage of 10 V. For higher power capability, fan

input voltage can be increased up to 15 V by U10 (IFX91041EJV, DC-DC voltage regulator), which controls the

fan voltage based on the PFC current sensing op-amp output voltage.

System power output capability

In order to test the total ouput power capability of the MADK system as in Figure 2, the DCB case temperature is

tested with different MADK output power.

Test conditions are: ambient temperature Ta=25 ℃, AC input voltage is VAC=220 V/50Hz, bus voltage is

VDC=380 V, PFC PWM frequency is 50 kHz and inverter frequency is 6 kHz.
