Summary:

With the increasing demand for efficient and clean transport solutions, applications such as road transport vehicles, aerospace and marine are seeing a rise in electrification at a significant rate. Irrespective of industries, the main source of power that enables electrification in mobility applications like electric vehicles (EV), electric ships and electrical vertical take-off and landing (e-VTOL) is primarily a battery making it fundamentally a DC system. Fast charging solutions for EVs and e-VTOLs are also found to be DC in nature because of several advantages like ease of integration, higher efficiency, et cetera Likewise, the key drivers of the electric grid are resulting in an energy transition towards renewable sources, that are also essentially DC in nature. Overall, these different business trends with their drivers appear to be converging towards DC power systems, making it pertinent. However, DC circuit protection poses serious challenges compared to AC due to the absence of natural zero-crossing points and the high rise rate of fault current demanding the need for fast-acting protective devices. Circuit breakers as protective devices are advantageous because of their resettable feature. This has prompted engineers to look beyond their conventional purview and explore developments in mechanical technologies of fast-acting switches and power electronics technologies to develop circuit protection solutions for DC systems. The result has been the development of solid-state circuit breakers (SSCB) and hybrid circuit breakers (HCB), making their design and analysis crucial.Thus, this paper focuses primarily on the model-based analysis of SSCB and HCB used for DC circuit protection in mobility applications. System-level models of the breakers are developed and integrated with a DC power distribution system. Key critical to quality (CTQs) of the design like response time, power loss, temperature rise, rate of rise of fault current, current commutation, and drop in DC bus voltage are predicted. Also, sensitivity to design parameters is analyzed. As there are a variety of architectures for these breakers, a Model-Based System Engineering (MBSE) approach is adopted to have an ideal framework for tracking and evaluating different architectures. Further, a Machine Learning (ML) based Reduced-Order Model (ROM) is developed, embedded in the MBSE framework for quick model-based sensitivity and optimization studies for faster product-to-market without compromising on accuracy
