What is the meaning of hiccups in switching power supplies?
I do not know, it should be high frequency oscillation for some reason to stop the vibration, and then start the vibration, so there will be hiccups.
Hiccups that the switching power supply in the output short circuit and other failures, the switching power supply chip after working hundreds of milliseconds and then stop working for a few seconds, and then start working hundreds of milliseconds, continuous cycle.
Hiccups Hic cups
When the power supply in the over-current, over-voltage and other abnormal working conditions:
Module control circuit to monitor the module exception -> control system ordered shutdown ->
For a period of time no output -> after the set the shutdown time system need to confirm whether the abnormal state is canceled at this time the module ordered boot Y abnormal state to eliminate the module follow-up normal work N abnormal state still exists return to the first step to continue the cycle
If the exception has been the existence of the module will be over a period of time to boot and then quickly shut down this is the hiccup
