Patent ID: 8902613

Claim:
An integrated converter, comprising: an input unit for receiving an electric-power signal transmitted by a power source; a boost inductor for being electrically coupled to the input unit; a buck-boost converter; a voltage regulator comprising: a first diode; a second diode; and a first transformer comprising: a primary winding for being electrically coupled to the buck-boost converter; and a secondary winding for being electrically coupled to the first diode and the second diode, wherein the voltage regulator is electrically coupled to the boost inductor through the first diode and the second diode, and is electrically coupled to the buck-boost converter through the first transformer; an energy-storing capacitor for being electrically coupled to the boost inductor and the voltage regulator; a single-ended switch for being electrically coupled to the buck-boost converter; and a control unit for being electrically coupled to the single-ended switch so as to optionally alter the electromotive force of the first transformer of the voltage regulator and further switch on the first diode or the second diode alternatively.
