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.
Inductor is one of the most critical components in solar inverters, mainly for energy storage, boosting, filtering, EMI elimination, etc. Using glue-filled inductance can reduce the temperature inside the solar inverter and the inductance, and can also significantly improve the inductance performance and longevity.
