Problems solved by technology

In order to meet the power requirements of electronic equipment, the power adapter developed for this type of electronic equipment usually adopts the LLC resonant architecture. This power architecture is suitable for high-power AC-DC power supplies above 90W, but the circuit of the power supply frame is complicated and the number of parts is large. high cost
In particular, as the power increases, the cost of necessary components such as transformers, power switch tubes, and synchronous rectifiers in the power adapter will increase significantly, and the volume will increase significantly, resulting in higher overall cost and volume of the power adapter. In addition, as the power increases, the loss of the power adapter increases significantly, resulting in lower efficiency of the power adapter

Embodiment Construction

[0041] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] Although the power supply of the flyback architecture is simple in structure and low in cost, its output power is small, so it is not suitable for powering high-power loads. Although a power supply with a resonant architecture can achieve relatively large output power, its structure is complex and its cost is relatively high. Whether it is a power supply with a flyback architecture or a power supply with a resonant architecture, they are all power supplies with a single power module, which cannot meet the requirements of high output power, simple structure, and low cost at the same time.

[0043]If a power architecture with multiple power modules connected in parallel is adopted, multiple powe...

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electronic equipment, and in particular, to a power supply system and electronic equipment. Background technique [0002] The power adapter is a power supply for small portable electronic devices and electronic appliances. Its working principle is to convert AC input into DC output. The power of the original electronic equipment is generally below 90W, and the power adapter generally adopts the flyback architecture. The power architecture is characterized by simple circuits, fewer parts, and lower cost. It is generally suitable for low-power AC-DC power supplies below 90W. However, with the improvement of data processing capability, graphics processing capability and display resolution of electronic devices, the power of electronic devices is increasing. Taking gaming laptops as an example, its power is usually above 300W, and even can reach 500W. In order to meet the power require...
