Embodiment Construction

[0039] As used throughout this specification, including the claims, the term "coupled (or connected)" may refer to any means of connection, direct or indirect. For example, if it is described that a first device is coupled (or connected) to a second device, it should be interpreted that the first device can be directly connected to the second device, or the first device can be connected to the second device through other devices or certain A connection means indirectly connected to the second device. Terms such as "first" and "second" mentioned in the entire specification (including claims) are used to name elements, or to distinguish different embodiments or ranges, and are not used to limit the number of elements. The upper or lower limit is not used to limit the order of the elements. In addition, wherever possible, elements / components / steps using the same reference numerals in the drawings and embodiments represent the same or similar parts. Elements / components / steps usi...

Abstract

The invention provides a multi-port power supply device and an operation method thereof. In an embodiment, the multi-port power supply device includes a plurality of USB connection ports, a plurality of power supply converters, and a common control circuit. The plurality of USB connection ports include a first USB connection port and a second USB connection port. The plurality of power supply converters are configured to supply power to the plurality of USB connection ports. The common control circuit is configured to learn the power variation of the plurality of USB connection ports, and correspondingly control the plurality of power converters to supply power to the plurality of USB connection ports according to power requirements of the plurality of USB connection ports. The common control circuit dynamically transfers a power difference between the first power of the first USB connection port at the first time and the second power of the first USB connection port at the second time to the second USB connection port.

Description

technical field [0001] The present invention relates to a power supply device, in particular to a multi-port power supply device with multiple connection ports and its operating method. Background technique [0002] Generally speaking, when the power supply device provides power to the external device through the USB connection port, the power supply device needs to perform voltage conversion operation according to the rated specification of the external device, so that the output voltage of the power supply device can meet the demand voltage of the external device . The power supply device may have a plurality of connection ports and a plurality of voltage converters corresponding to the plurality of connection ports, so as to simultaneously provide power of different output voltages to a plurality of external devices with different required voltages. In any case, once the power configuration between the power supply device and a certain external device is determined, the ...
