This paper proposes an approach to simplify the proposed halt sequence of an inverter without the pole position information of a permanent magnet synchronous motor. When the Back-to-back (BTB) system with a small capacitor is stopped by the grid faults during motor regeneration, the DC-link capacitor voltage is increased rapidly if all gates in the BTB system are turned off at the same time. Therefore,...
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 in passive mode (with all IGBTs switched...
