Temperature rise considerations and calculation example

According to the previous mathematical formula, it is possible to simulate (with an accurate

software tool) the STGIPS10K60A performances, under certain application conditions.

Figure 17

shows the results (IC(RMS) current - which is related to the output motor power vs.

fsw) of the power loss simulations.

Maximum IC(RMS) current vs. switching frequency

●

Condition: VPN=300 V, VCC=VBS=15 V, VCE(sat)=typical, switching loss=typical,

Tj=125 °C, Tc=see graph, Rth(j-c) = max., ma=0.8, PF=0.6, 3-phase continuous PWM

modulation, 60 Hz sine waveform output.

Note:

The above characteristics may vary in the different control schemes and motor drive types.
