A novel power supply apparatus () includes a microcontroller () and a plurality of voltage converters (). If the voltage converters () are in a boost mode and a plurality of duty cycles of the voltage converters () calculated by the microcontroller () are less than 0.5, the microcontroller () is configured to limit at least one of the duty cycles of the voltage converters () to 0.5. If the voltage converters () are in a buck mode and the duty cycles of the voltage converters () calculated by the microcontroller () are greater than 0.5, the microcontroller () is configured to limit at least one of the duty cycles of the voltage converters () to 0.5.

Multi-phase converter including a duty cycle limiter

A power supply apparatus () suppressing a transient voltage is applied to an input voltage (). The power supply apparatus () includes a power supply circuit (), a feedback signal generation circuit () and a feedback signal control circuit (). If the power supply circuit () stops receiving the input voltage (), the feedback signal control circuit () controls the feedback signal generation circuit () to discharge so that the feedback signal generation circuit () controls the power supply circuit () to decrease an output voltage (), so that when the power supply circuit () receives the input voltage () again, the power supply circuit () avoids generating an output overvoltage condition for the output voltage ().
