A method of digital simulation analysis is introduced regarding asynchronous motor system driven by voltage source PWM inverter. On the basis of simulating models of inverter and asynchronous motor, the interface of those two models has been studied and the system simulation method is presented. Running results from computer coincide with the experimental report, then the effectiveness and reliability of this simulation analysis programme can be verified. The method is also available for simulation analysis on any other thyristor-inverter driven asynchronous motor system.
