THERMAL CONSIDERATION

Thermal management is an important part of the system design. To ensure proper, reliable operation,

sufficient cooling of the power module is needed over the entire temperature range of the module. Conduction

cooling is usually the dominant mode of heat transfer.

Thermal Testing Setup

The following figure shows the testing setup in which the power module is mounted on an Al plate and

was cooled by cooling liquid.

Figure 10: Thermal test setup

THERMALDERATING CURVE

The following figure shows the location to monitor the temperature of the module’s baseplate. The

baseplate temperature in thermal curve is a reference for customer to make thermal evaluation and make sure

the module is operated under allowable temperature. (Thermal curves shown in Figure12 are based on different

input voltage).
