Background

An Inductor (Inductor) is a component that can convert electrical energy into magnetic energy for storage. The inductor is similar in structure to a transformer, but has only one winding. The inductor has an inductance that only impedes the change in current. If the inductor is in a state where no current is passing, it will try to block the current from flowing through it when the circuit is on; if the inductor is in a current passing state, the inductor will try to keep the current unchanged when the circuit is opened. Inductors are also known as chokes, reactors, dynamic reactors. The inductance coil generates a low amount of heat during operation, but if the amount of heat is too high, the following three cases are generally used: firstly, the inductance coil wire is too thin, which causes the resistance of the inductor to be very large, and the inductor can generate heat under the condition that the effective value of the current is certain; secondly, the inductance is saturated, and the heat generation is common in the condition; thirdly, the inductor coil is heated due to the existence of larger oscillating voltage in the circuit; the inductance coil heat dissipation is usually through using cooling fan to drive heat, perhaps cools down inductance coil through scribbling heat dissipation coating, and heat dissipation coating accumulates the intensification through the heat absorption and radiates the heat dissipation to external space, can also keep insulating, anticorrosive, dampproofing etc. is the influence that the inductance coil generates heat and causes the circuit that reduces more neotype.
