What is the reason for the heating of the inductance coil of the inductance magnetic winding wire?

Winding inductors heat up because the coil resistance is very low. After 220V voltage is added, a large current will be generated. If the current is large, it will be very hot. You can try to increase the voltage frequency, the frequency increases, the inductance increases, and the current decreases. This power supply has two identical inductances, one in the positive pole and one in the negative pole (not broken). The magnetic loop inductance is directly in front of the controllable field tube without other capacitors, and the two are connected in series with one positive and one negative. The inductance energizes a coil, and a controlled pulsed direct current is given by the front-end tube.

1. The inductance coil wire is too thin, which will cause the resistance of the inductance to be very large. When the effective value of the current is constant, it is normal for the pole to heat up.

2. There is a large oscillating voltage across the inductor.

3. The inductance is saturated, and this kind of heating is also common. It is recommended that you change the magnetic core to a larger one, which can reduce the number of turns and shorten the line length. Forward conversion, small ripple current, small magnetic loss, mainly due to resistance heating.
