VFDS AND MAXIMUM INRUSH CURRENT - ABB
library.e.abb.comLow inrush current is an inherent advantage for a PWM VFD over other control methods because of the way a VFD will control the motor flux while starting up a motor. The reason for this comes from a basic understanding of VFD design. Drives manage the flux of the motor. The motor’s magnetic flux will be
Unipolar and Bipolar PWM Inverter
www.ijirst.orgbut output current distortion and efficiency are the two main parameters for the selection of inverters. Two such topologies are described herein. In this paper, the SPWM (Sinusoidal Pulse Width Modulation) technique of unipolar and bipolar inverters is presented and the models are simulated in MATLAB – Simulink.
