Analytical Design Optimization of PFC Boost Inductor in CCM

This paper describes in details an analytical design optimization procedure of the PFC Boost inductor working in continuous conduction mode of the current. The method finds an optimal solution based on the inductor's minimum power loss and its geometrical volume, the factors, which depend on assumed PFC working conditions. Moreover, the method sweeps through the magnetic flux densities and inductor current ripples assuring rejection of these inductors, which are not possible to build, otherwise delivering 2D and 3D matrices of optimal designs.
