The very high switching speed of wide bandgap semiconductor devices enables higher switching frequencies at lower losses. However, it can also cause negative effects on the insulation material. For investigating the effect of steep voltage slopes on interwinding insulation systems, a gallium nitride based full-bridge converter with digitally adjustable voltage slopes is developed and presented within this article.
