13.2.2 Improvement of the derating
・
Derating properties are improved by attaching optional FFM to an applicable model. Neither applicable
model needs the derating of the carrier frequency and the current derating at ambient temperature 50
℃
.
The detail refers to figure 5 ,6 and figure 7
13.2.3 Capacitor life improvement
・ Bus capacitor life doubles approximately when I attach optional FFM to an applicable model.
The detail refers to figure 8
