When the high frequency transformer core is saturated, the current in the coil increases, and the transformer heats up and generates self-excited oscillation. The oscillation of the coil causes the surrounding air to vibrate and make noise.

Tips:Power supply load problem

Under the condition of no load or light load, the switching power supply will oscillate at some operating points, which is manifested as the noise of high frequency transformer and the instability of output. Happen this kind of phenomenon is due to the light/light load, the switch instantaneous opening is too big, too much time to output energy and voltage overshoot is big, need a long time to return to normal voltage, so switch to stop work for a period of time, this switch is working in the intermittent work mode, the transformer in low frequency (regular intermittent full cutoff period or the frequency of the dramatic change duty ratio) of vibration.
Transformer work in a serious overload state, the moment may burn - this is the source of many power before burning "scream".
