1. High-Frequency Voltage Distribution Modelling of a Slotless PMSM from a Machine Design Perspective
Master-uppsats, KTH/ElkraftteknikSammanfattning : The introduction of inverters utilizing wide band-gap semiconductors allow for higher switching frequency and improved machine drive energy efficiency. However, inverter switching results in fast voltage surges which cause overvoltage at the stator terminals and uneven voltage distribution in the stator winding. LÄS MER
