The higher the switching frequency, the greater the frequency converter loss, the greater the power module heat generation, and the impact on efficiency. The loss is more significant at high voltage. When the switching frequency is high, the current waveform is smooth, reducing harmonic interference. At low frequency, the motor loss increases.
Switching frequency and inverter power consumption
The higher the switching frequency, the greater the loss of the inverter, the greater the heat generation of the power module, and the impact on efficiency. The loss is more significant at high voltage.
The impact of switching frequency on the output current of the inverter
When the switching frequency is high, the current waveform is smooth, reducing harmonic interference. At low frequency, the motor loss increases.
The impact of switching frequency on the motor
The high switching frequency reduces noise and vibration, but increases power loss.
