Abstract
A circuit for automatically operating a switching power supply is capable of operating from first and second input voltage ranges. The circuit changes the switching power supply from a full-wave rectifier circuit to a voltage doubler rectifier circuit by electrically connecting first and second nodes. The circuit includes a rectifier circuit and a voltage level sensing device for generating an output voltage to trigger a triac, which connects the first and second nodes.
