Power reduction due to the line voltage
Switching losses in the power semiconductors rise with increasing line voltage and increasing fPWM. Observe the following power-reducing characteristic values:
Line voltage VlineThe power-reducing characteristic values between 400 V and 500 V are proportional | fPWM | ICont/IN |
|---|---|---|
400 V | 4 kHz | 100% |
8 kHz | 75% | |
16 kHz | 50% | |
37% for MDA90A-0480.. | ||
