1. A power supply apparatus (10) comprising:
a microcontroller (102); and
a plurality of voltage converters (104) electrically connected to each other and electrically connected to the microcontroller (102),
wherein if the voltage converters (104) are in a boost mode and a plurality of duty cycles of the voltage converters (104) calculated by the microcontroller (102) are less than 0.5, the microcontroller (102) is configured to limit at least one of the duty cycles of the voltage converters (104) to 0.5;
wherein if the voltage converters (104) are in a buck mode and the duty cycles of the voltage converters (104) calculated by the microcontroller (102) are greater than 0.5, the microcontroller (102) is configured to limit at least one of the duty cycles of the voltage converters (104) to 0.5.
