Abstract:
1. A method of controlling a power supply current to a load, which comprises: sensing an input voltage of a power control circuit that is representative of an output voltage error; sensing a voltage that is representative of an output load current; if an excess current threshold is exceeded, interrupting the supply of load current for a predetermined period of time; turning the power supply back on to supply load current as long as the excess current threshold is not exceeded; if the current exceeds the excess current threshold, interrupting the load current again and repeating a cycle of operation, wherein if the load is changed such that the excess current is not exceeded when the supply current is turned back on, continuing to supply current without interruption and user intervention; and establishing a voltage threshold at an input connected to a power supply control module by measuring input bulk DC voltage corresponding to a rectified AC input voltage such that the voltage at the input increases when there is an increase in load and a decrease in AC input voltage.
