Different from regular PM machines, flux modulation machines are with different stator and rotor pole numbers, and produce steady torque based on the so called flux modulation effect. The special operation principle makes flux modulation machines high-torque density and low-pulsation torque, and more design freedoms lead to many novel machine topologies for different applications. This webinar will be a summarized presentation of Flux Modulation Machines: from principle, features to topologies. After a short introduction, the Webinar will focus on machine family definition and difference with traditional machines, operation principles, and topologies. After introducing three machine major components: flux modulator, armature and excitation field, different flux modulation machine topologies will be introduced based on different rotating components. Common features will be summarized, main concerns and challenges will also be discussed. At the end, analyses, designs, and prototypes of vernier machines, a flux-modulation machine family member, will be demonstrated. Read More...

The presentation will discuss major SiC power device application areas and touch on foundry models, cost reduction strategies, and path to commercialization. The advantages of SiC over other power electronic materials will be outlined, and SiC devices developed for power electronic applications will be introduced. Emphasis will be placed on SiC MOSFETs, which are currently being inserted in the majority of SiC based power electronic systems. Aspects of device fabrication will be summarized, stressing processes that do not carry over from the mature Si manufacturing world and are thus specific to SiC. Finally, the presentation will highlight common SiC Edge Termination techniques, which allow power devices to reach their full high-voltage potential. Read More...
