This paper presents real-time simulation results of a Permanent Magnet Synchronous Machine (PMSM) Drive in faulty and non-standard modes and validates these against an actual industrial PMSM drive system. The paper will put emphasis on the test of special and faulty modes in PMSM drives. Results of real-time simulation of a PMSM drive with an open phase and(More)
This paper presents a real-time electro-thermal simulation system which is a novel method of estimating the junction temperatures of power semiconductors. It calculates the junction temperatures of the power semiconductors in real time. The load current and the output voltage of an actual power conversion system are detected to calculate the instantaneous(More)
