Inductor is one of passive components which is transfer between electronic and magnetic & which resists changes in electric current passing through it. Energy is stored in the magnetic field in the inductor as long as current flows. When the current flowing through an inductor changes, the time-varying magnetic field induces a voltage in the conductor. Inductor can be application in the circuit of Buck DC-DC Converter, Boost DC-DC Converter, Filter, Impedance matching, EMI noise suppressor…
