3.2.2 performance according to carreir frequency
Fig.3-2-2 shows the typical characteristics of allowable effective current vs. carrier frequency under the following
inverter operating conditions based on power loss simulation results for 1200V series. And Fig.3-2-3
shows for PSS50xC1F6.
Fig.3-2-2 Effective current-carrier frequency characteristics
Fig.3-2-3 Effective current-carrier frequency characteristics
Fig.3-2-2 and Fig.3-2-3 show one of the example of estimating allowable inverter output effective current with
different carrier frequency and allowable maximum operating temperature condition (T
c
=100°C. T
j
=125°C). The
results may change for different control strategy and motor types. Anyway please ensure that there is no large
current over device rating flowing continuously.
