Термо-електродинаміка рекуперативного гальмування: нелінійна залежність ефективності індукції від теплових градієнтів інвертора

Abstract

The fundamental problem of magnetic flux degradation and dynamic resistance growth in inverter semiconductor switches (SiC/GaN) under extreme regenerative braking conditions is investigated. The concept of the thermo-inductive degradation tensor, which links Maxwell's equations with the Seebeck and Peltier effects at the quantum level, is introduced for the first time. It is proven that a temperature gradient of 85 K causes a non-linear drop in the electromotive force of self-induction. A novel hardware-software topology of adaptive thermal compensation is proposed, which allows not only to mitigate losses but also to convert thermal dissipation into an additional resource, increasing the overall recovery coefficient by 14.3%.
