• • • Transformer Design with Magnetics Ferrite Cores Magnetics offers two methods to select a ferrite core for a power application: core selection by power handling capacity and core selection by WaAc product. Core Selection by Power Handling Capacity The characterizes the power handling capacity of each ferrite core based upon the frequency of operation, the circuit topology, the flux level selected, and the amount of power required by the circuit. If these four specifics are known, the core can be selected from the Typical Power Handling Chart. Core Selection by WaAc Product The power handling capacity of a transformer core can also be determined by its WaAc product, where Wa is the available core window area, and Ac is the effective core cross-sectional area. Using the equation shown below, calculate the WaAc product and then use the to select the appropriate core. WaAc = Product of window area and core area (cm 4) P o = Power Out (watts) D cma = Current Density (cir.
