Abstract

Adverse effects in voltage source inverter-fed drive systems are discussed. The paper focuses on the adverse influence of voltage source inverter on the fed motors. A very important part of the analysis is a model of the motor, especially determination of motor high frequency characteristics. Several representations (one-phase and three-phase) of the motor and the cable suitable for determination of motor transient overvoltage have been proposed. Factors contributing to the motor overvoltage are described. Influence of cable length, du/dt (rise time t _ON) of voltage pulses and motor characteristics is investigated. The results are compared with data obtained from a number of experiments and simulations
