Abstract
A short protection method for a power converter having an output terminal for providing an output voltage. The power converter works in a hiccup protection mode when a short fault occurs. The hiccup protection mode has a sleep stage and a reset stage, the short protection method detects the output voltage during the hiccup protection mode and sets the time period of the reset stage based on the detected output voltage. The time period of the reset stage increases with the increase of the detected output voltage.
