Description

Background
The most widely used scenario of inductors is that a power supply, a boost circuit and a buck circuit all need to have an inductor to store energy and release energy. All the voltage boosting and reducing circuits use the important principle that the inductance current can not change suddenly. I.e. the current in the inductor has inertia, which is the energy stored by the inductor. When the switch is turned on, the inductor stores energy, and when the switch is turned off, the current of the inductor to the ground is cut off, but the current on the inductor cannot disappear immediately, a leakage path needs to be found, and then the current runs to a load end. The load does not consume so much current that the current in the inductor becomes the voltage across the load, raising the voltage. In the next cycle, the switch is opened, the inductor generates current, although the voltage on the right side of the diode is higher than that on the left side, the current cannot flow in the reverse direction, and the high voltage is maintained. The switch is then closed again, the inductor releases energy to the load again, and the voltage continues to rise. The inductor is charged and discharged continuously in such a circulation way, so that the voltage boosting is achieved.
