The reason for capacitor discharge is to convert electric energy and release electric energy, thus storing chip inductance and current. The resistance consumes electric energy and converts it into heat, and no longer releases heat. Capacitors convert electrical energy into potential energy. The chip power inductor converts electrical energy into magnetic energy potential and discharges it. Magnetic energy can generate electricity, while thermal energy cannot be converted by resistance. Therefore, resistance consumes energy.

Inductors and capacitors both block current. Inductor is the function of keeping current. The inductor is connected to direct current, because direct current is not important, because the magnetic field will not change. The capacitor is kept at a voltage and connected to the integrated circuit through the integrated circuit, because the capacitance in the integrated circuit is equivalent to an open circuit, while the capacitor keeps the voltage.

According to Lenz's law, when I increases, the direction of induced current is opposite to I. when the induction coil is energized, the current changes rapidly and the induced current is large. When it is superimposed with the original current, the current in the coil can only increase from 0 to 0 until the change of current tends to 0. At this point, he row will change from 0 to 0. The current in the coil is relatively large. Therefore, the inductance coil will have a delay effect.

The filter function can also be realized by using the power inductance of the patch, which is combined with the capacitor to form different filter circuits. Image: Filters are alternating signals that prevent fluctuations. Therefore, the alternating component is the filtered object, and the filtered alternating component can obtain pure DC component. Generally, the filter function of the chip inductor is realized after the power supply rectifier circuit.
