Embodiment Construction

[0035] see figure 1 As shown, the multi-output power supply of the present invention includes a first output port O / P1, a second output port O / P2, a power conversion module 10, a first switching module 20 and a second switching module Module 30. The power conversion module 10 has a first power output terminal N1 and a second power output terminal N2, and the power conversion module 10 converts an AC input power AC and generates a first output power and a second output power Power supply, the first output power is output from the first power output terminal N1, and the second output power is output from the second power output terminal N2, the rated power of the first power output terminal N1 and the second power output terminal N2 Power is preferably not the same. An input end of the first switching module 20 is electrically connected to the first power output end N1, and two output ends of the first switching module 20 are electrically connected to the first output port O / ...

Abstract

The invention provides a multi-output power supply and a power distribution control method thereof. The multi-output power supply comprises a power conversion module and two switching modules, and two power output ends of the power conversion module are selectively connected or not connected with two external output ports through the two switching modules respectively. Therefore, the power supply can control which power output end supplies power to which power output port or control the two power output ends to output power in a combined mode according to the required power of the two output ports and the rated power of the two power output ends. Therefore, the two power output ends of the power conversion module can be optimally designed for different rated powers respectively, the design range of the optimal conversion efficiency is enlarged, a user does not need to select different output ports according to the different rated powers, and meanwhile, the purpose of improving the use convenience is achieved.

Description

technical field [0001] A power supply and its power distribution control method, especially a multi-output power supply and its power distribution control method. Background technique [0002] In recent years, consumer electronic products have become more and more diverse and close to the needs of life. Most users often carry more than one electronic product with them, and often include electronic products that require higher output power, such as existing tablet computers or laptops. The rated required power is, for example, 45W or more. Therefore, a power supply has multiple output ports, each of which can provide output power at the same time, and a single output port has a larger total output power is one of the main demand products. [0003] see Figure 10 As shown, in response to the above requirements, the existing multi-output power supply device includes a first AC-DC conversion unit A / D1, a second AC-DC conversion unit A / D2, a first switch SW1, a second switch SW2...
