| Abstract: | Over-voltage produced in PWM inverter-driven systems and its relationship with cableparameters are introduced. By tests and simulation, the current and voltage distribution characteristics onthe stator winding of PWM inverter-fed motor are investigated. The countermeasures of improving voltagedistribution and enhancing the corona-resistance isolation life of motor windings are presented. |
