A numerical model is used to study the influence of cooling on inductor design. Various Pareto optimal designs of air-cooled inductors with bar and foil winding are compared to an existing di/dt choke with air core and direct water cooling. In air co

A power electronic device's lifetime depends on its maximum operating temperature and the temperature swings it is subjected to. Heat sinks employing phase change materials (PCMs) can be employed to achieve a temperature reduction, but only for a lim

Cooling systems take a significant portion of the total mass and/or volume of power electronic systems. In order to design a converter with high power density, it is necessary to minimize the converter's cooling system volume for a given maximum tole

∗Power semiconductors can be modeled as a thermal network of resistors and capacitors. The thermal boundary condition of such a model is typically defined as the heat sink surface temperature, which is assumed to be constant. In reality, the heat s
