Abstract
An electronic device is provided. The electronic device includes a plurality of load units, a plurality of serial-parallel switch units and a control module. The control module switches the serial-parallel switch units to a first state or a second state according to a level variation of an input voltage. Connection relations of the load units are correspondingly changed according to the level variation of the input voltage. In this way, the electronic device can be driven by an alternating-current voltage.
