Abstract
An automatic power supply converting circuit includes a live input terminal, a neutral input terminal, a relay, a regulator, a voltage divider circuit, an identifying circuit, a switch circuit and a voltage doubling circuit. The live input terminal and the neutral input terminal are configured for receiving a first alternating current (AC) voltage. The regulator is configured for filtering and steadying the first AC voltage and outputting a regulated voltage. The voltage divider circuit is configured for sampling the first AC voltage and outputting a divided voltage. The identifying circuit is configured for comparing a divided voltage with a reference voltage, and outputting a control signal. The switch circuit is configured for controlling the relay to be conductive or not. The voltage doubling circuit is capable of being controlled by the relay and outputting a doubled voltage.
