Buck circuit energy storage inductor
energy stored by the inductor increases only while the current is building up to its steady-state value. When the current remains constant, the energy stored in the magnetic field is also constant. If we connect an ideal inductor to a voltage source having no internal resistance, the voltage across the inductance must remain equal to the applied voltage.
