Abstract

This paper presents simulation results by using Matlab/Simulink for the assessment of harmonic and interharmonic currents generated by the voltage source inverter (VSI)-fed adjustable speed drives (ASDs). In the simulation, the commutation effects caused by source impedance and non-ideal supply voltages are included. The front-end converter, dc link, pulse-width modulated (PWM) inverter, and the induction moter of the ASD are modeled in detail. Results are then compared with those obtained by laboratory tests to show the solution accuracy. Numerical and measurement experiences show that the adopted simulation tool yields satisfactory results for harmonic and interharmonic current assessments of VSI-fed ASDs.
