讲座摘要：
Power electronics and power conversion in general is today part of every segmentof our life. Any piece of electric equipment we have today is somehow based on power electronicsand converters; home appliance, industrial equipment, renewable energy, automotive, avionicetc., etc. Conversion efficiency, specific power, power density and converter cost are today themost critical requirements for new converters.
In last decade, we have seen dramatic progress, particularly in the field of powersemiconductors. Each new generation of power semiconductor introduces new challenges andissues, Some of the issues such as high di/dt and du/dt in combination with parasitic inductanceand capacitance of the device and package make almost impossible to fully utilize advantages ofnew power semiconductors (SiC and GaN). One way to increase the conversion efficiency andreduce cost/size/weight is to deploy Multi-Level and/or Multi-Cell converters and Partial Power Rated (Processing) power concept.
The objective of this tutorial is to fully explore Pros and Cons of Multi-Level and Partial PowerRated (Processing) converters. Advantages of these topologies, such as significant reduction ofthe filter and the dc bus capacitor size will be extensively discussed. Moreover, strong impact onthe device switching performances including switching loses and the switch over-voltage stresswill be addressed too. A short design guideline for different concepts will be discussed too.
Several case studies and design examples are given in concluding part of the tutorial. Oneparticular design example presented in the tutorial is 25kW battery interface dc/dc conyerter. Anextraordinary efficiency of 99.5%, specific power of 30kW/kg and power density of 50kW/dm3nave been achieved.
This tutorial is aimed at power electronics engineers and graduate students who want toimprove their knowledge and understanding of Multi-Cell, Multi-Level and Partial Power Ratedconverters and their application, nowadays as well as in the near future.
