Inductor losses may be estimated using readily available data from core and inductor suppliers along with the relevant power supply application parameters. An inductor consists of wire wound around a core of ferrite material that includes an air gap. A subset within the broad inductor category, power inductors operate as energy-storage devices.
In such cases, the current, I, flowing through the inductor keeps rising linearly, as shown in Figure 1 (b). Also, the voltage source supplies the ideal inductor with electrical energy at the rate of p = E *I. Without the internal resistance, the inductor is lossless because it cannot produce heat or light from the available energy.
Thus, the power delivered to the inductor p = v *i is also zero, which means that the rate of energy storage is zero as well. Therefore, the energy is only stored inside the inductor before its current reaches its maximum steady-state value, Im. After the current becomes constant, the energy within the magnetic becomes constant as well.
