Impact of cable line parameters on pulsed surges in asynchronous frequency controlled electric drives.
Abstract
The equivalent scheme of the system is developed for the autonomous voltage inverter with a pulse-width modulation-asynchronous motor, which takes into account the distributed parameters of the cable line. Specified expressions are specified for calculating the voltage at any point of the cable line between the inverter and the motor and the critical length of the cable, which corresponds to the appearance of maximum overvoltages.
