This paper presents the results of thermal modeling of a unique 69 kV 3000A Solid State Fault Current Limiter (SSFCL) developed by Silicon Power of Malvern, PA with support of EPRI. The development of the Solid State Fault Current Limiter is expected to modernize power distribution systems through the use of small-scale solid-state power devices. The use of this new design is expected to increase reliability and functionality while reducing footprint. However, as the footprint is reduced, the heat flux for the system is increased, leading to the significant possibility of device failure due to thermal excursions if the heat load is not properly managed. The high heat loading requires the use of aggressive thermal management in the form of liquid cooling of the electronics. This system features 288 kW of waste heat in the three phase system. The system is submerged in FR3 dielectric coolant and the desired thermal management system is liquid natural convection within the tank and shed to the ambient through an external finned array system. This project explores the feasibility of this system design.

The thermal management of high density power electronics can be extremely challenging due to high power loads paired with small device footprints. When these power electronics are used in systems, which require extremely high reliability, the design of the thermal abatement system takes on increasing importance. In this study, the thermal response of a solid state fault current limiter is analyzed in steady-state and failure mode to develop a thermal solution which is both economical and reliable. The solid state fault current limiter is used in electric distribution systems to prevent a current surge from reaching sensitive equipment downstream of a power plant in the event of a disturbance on the line. A parametric study on several design variables including power loading, device spacing, and system flowrate is completed to give insight into the development of an optimal design. A coldplate design using dielectric mineral oil, which minimizes both system footprint and operating cost, is developed. This analysis and thermal management solution is applicable not only to this situation but also to the other high density power electronics applications.
