The Challenge of Insulation Coordination Greater than 400 Volts


The manufacturing of reliable power electronics in the range of 400-500 V or even future voltages of 800-1200 V requires not only technical design and high-quality facilities but also in-depth production expertise. Similar to cooking, where the quality of the meal depends heavily on the chef rather than the kitchen equipment, experience in production plays a crucial role in preventing potential breakdowns or discharges between high voltage potentials. Previous empirical values and standards related to voltages up to 60 V are only partially applicable. Deepen your understanding of this topic in this specialized article.
