摘要： A power supply device for providing an output voltage includes a first resonant converter, a second resonant converter, a first converting circuit, and a current regulating circuit. The first resonant converter is for converting a first input voltage into the output voltage. The second resonant converter is for converting a second input voltage into the output voltage. The output ends of the first and second resonant converters are coupled in parallel. The first converting circuit is coupled to the first resonant converter and is operable to provide the first input voltage to the first resonant converter. The current regulating circuit receives signals related to output currents of the first and second resonant converters, and drives operation of the first converting circuit according to the signals received thereby such that the output currents of the first and second resonant converters have substantially equal magnitudes.
