Detailed electrical and thermal models of power electronics systems require a significant amount of computational resources and processing power, making the implementations for real-time simulation even more challenging. This paper presents a real-time thermal electrical co-simulation method for power
electronics applications. The proposed approach allows independent development of electrical and thermal models without implications to modeling or computational requirements for each
simulator. Two approaches based on a detailed and an average loss model are developed. Extensive results and a comparison between possible approaches demonstrates how real-time cosimulation
can allow efficient electrical and thermal modeling expanding the nature of multi-physics simulations applied in power electronics converters.
