摘要： A novel power supply apparatus (10) includes a microcontroller (102) and a plurality of voltage converters (104). 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. 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.

摘要： A power converter includes a first contact, a second contact, a third contact, a fourth contact, a first ground contact, a second ground contact, a transformer, and a first switching element to a fifth switching element. The first switching element to the fifth switching element is controllable to switch on or off to form a first configuration and a second configuration, wherein the first configuration allows a power input to the first contact to be transmitted to the third contact through a first side of the transformer, and the second configuration allows a power input to the second contact to be transmitted to the fourth contact through the first side to a second side of the transformer, thereby to distribute the DC power in the same circuit structure.
