Hi all,
I have a question about reflection phenomenon in inverter-fed motors with long cable; I know the severity of the phenomenon is dependent on the magnitude of voltage stair (for two-level inverter it is VDC (DC link voltage) ) and the rising and falling time of the voltage. My question is that does switching frequency (carrier frequency of PWM) have any effect on exacerbation or soothing this phenomenon? if yes, how?
Thank you
