How to solve the problem of heat generation after the chip inductor is saturated?

The heating of the inductor coil is due to the low resistance of the coil. When the 220V voltage is added, a large current will be generated. When the current is large, it will be very hot. You can try to increase the voltage frequency. When the frequency increases, the inductance increases, and the current is small.

1. The wire diameter is too thin, which will cause the resistance of the inductor to be very large. When the effective value of the current is constant, it is normal for the inductor to heat up.
2. The inductor is saturated. This kind of heating is also very common.
3. There is a large oscillating voltage at both ends of the inductor.

It is recommended to change the magnetic core to a larger size, which can reduce the number of turns and shorten the line length. The positive chip power inductor manufacturer excites the conversion, the ripple current is small, the magnetic loss is small, mainly the resistance heat, check the filter capacitor, and the capacitor failure will cause the inductor to overheat and discolor.

Is the chip inductor magnetic bead connected behind the rectifier tube? If there is a filter capacitor at the front end of the inductor, please check whether it is open circuit.

At this moment, the power supply has two identical inductors, one in series with the positive pole and the other in series with the negative pole (not broken). There is a controllable field tube directly in front of the inductor without other capacitors. A coil is energized through these two inductors, one positive and one negative, and the controlled pulse direct current is given by the front tube.

1. The wire diameter is too thin, which will cause the resistance of the inductor to be very large. When the effective value of the current is fixed, it is normal for the pole to heat up.
2. There is a large oscillating voltage at both ends of the stacked inductor.
3. The chip inductor is saturated. This kind of heating is also very common. Change the magnetic core to a larger size, which can reduce the number of turns and shorten the line length. Forward conversion, small ripple current, small magnetic loss, mainly resistance heat.
