HOW TO DRIVE MOSFETs AND IGBTs INTO THE 21ST CENTURY

摘要

As the industry pushes for higher power levels and higher switching frequencies, power supplies, which use MOSFETs/IGBTs for power conversion, are being designed to their ultimate attainable efficiency, smallest footprint, size and weight. The subject of driving MOSFETs/IGBTs to their highest possible frequencies at the highest possible power levels, still providing protection, is multi-dimensional and requires knowledge of MOSFETs and IGBTs as well as circuit theory and how it applies to this discipline. Many topologies in high voltage converter, inverter and matrix converter applications require special techniques to drive MOSFETs and IGBTs. The paper deals with this subject and explains with examples how to face the challenges of tomorrow today.
