The study on convertor drive characteristics of permanent magnet generator for diesel electric propulsion system

Abstract

This paper describes the inverter drive characteristics of a 2.4 MW permanent magnet generator (PMG) for a diesel electric propulsion system. We demonstrated the relations between the PWM (Pulse-Width Modulation) pulse patterns and temperature rise in a permanent magnet in a PMG. Additionally, we demonstrated that inverter failure has a significant impact on the current and torque in a PMG.
