A hybrid core reactor is proposed based on silicon-steel and amorphous alloy in this paper. Amorphous alloy is used as core legs and siliconsteel is used as yoke core in the designed reactor, The electromagnetic and thermal field coupled model is built using three-dimensional finite element method. Compared with the conventional silicon-steel core reactor, the simulation results show that the designed hybrid core reactor can reduce eddycurrent loss and temperature rise.
