Abstract

This paper presents a description and results of the fastest-ever-reported, PC-based real-time (RT) simulator of an AC drive. The RT simulator is used to simulate a complete PMSM drive circuit in a Hardware-In-The-Loop (HIL) application. This consists of a PMSM fed by a 3-phase IGBT inverter, a DC link capacitor and a 3-phase diode bridge. This drive model runs on RT-LAB electric drive simulator and is connected to an external controller by analog and digital inputs and outputs for closed loop operation. The main innovation in this work is that the real-time simulation cycle is as low as 10 μs, which constitutes –to our knowledge- the shortest RT simulation time step ever reported for electric drives with this level of details in modeling the drive circuit.
