Test results

The output power capability of the EVAL-M7-HVMOS-INV power board was tested at different carrier
frequencies. The MOSFET case temperature is up to 100℃ under test conditions. All the tests take place at
room temperature and without heatsink or cooling fan. Figure 21 shows the increase of MOSFET case
temperature in relation to input power at different PWM frequencies. Figure 22 shows the motor-phase current
at different PWM frequencies.
