Problems solved by technology

If all parts of the power supply unit are designed separately, it will result in an increase in the cost and size of the power supply unit
Existing devices mainly integrate AC / DC and DC / DC converters, which is difficult to meet the cost and volume requirements of power supply devices
[0005] In the existing multi-channel power supply device, the output voltage and power quality often change with the input voltage and terminal load, and the voltage at the output port has disadvantages such as fluctuations, harmonics, and detuning. Ports and output ports are not interchangeable

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a multi-channel power supply integrated assembly and a control method thereof. Background technique [0002] In the prior art, the input ports of the AC and DC power input devices are fixed and cannot be exchanged with each other. For occasions that can only provide AC power, the DC power input device is often unusable, and for occasions that can only provide DC power, the AC The power input device is often unusable, causing inconvenience to users. [0003] As the types and uses of portable terminal products continue to increase, the requirements for the power supply of portable chargers are also getting higher and higher. The existing portable charging power supply mainly uses two power supplies for wired charging and wireless charging, and one charging power supply cannot meet the requirements of wired charging and wireless charging at the same time. [0004] The usual...
