Description

Technical Field

[0001] The present invention relates to the technical field of power supply control, and in particular to a power supply control device, a power supply control method and a power supply control system. Background Art

[0002] Traditional power supply control devices usually use hard switching technology, that is, switching operations are performed when the current and voltage are high. The biggest problem with this technology is that the switching loss is large, resulting in low system efficiency. With the increase of switching frequency, the high-frequency harmonics and electromagnetic interference (EMI) problems generated during hard switching operations are becoming increasingly serious, and cannot meet the needs of efficient and low-loss energy conversion. At the same time, the high-frequency harmonics in the system will interfere with the normal operation of other electrical equipment, causing electromagnetic compatibility problems to become more prominent. In addition, in the electromagnetic compatibility design of traditional power supply control devices, electromagnetic interference is usually reduced by adding shielding layers or filters. However, this passive shielding method not only increases the size and cost of the device, but also fails to achieve real-time control of dynamic electromagnetic interference. In complex industrial application scenarios, the dynamic changes in the electromagnetic environment often lead to unstable electromagnetic interference. The anti-interference design of existing devices is difficult to adapt to such changes, resulting in unstable system performance.

[0003] Although high switching frequency helps to reduce the size of electrical components and improve the response speed of the system, it also brings more serious electromagnetic interference problems. The high-frequency harmonics generated by high-frequency switching operations will cause electromagnetic interference, causing interference to other electrical components in the system, especially causing adverse effects on adjacent signal transmission lines, sensors and other sensitive devices. This situation is particularly common in scenarios such as consumer electronic devices, communication base stations, and industrial automation equipment. In severe cases, it may even cause equipment failure or malfunction. Summary of the invention

[0004] Based on this, it is necessary for the present invention to provide a power supply control device and a power supply control method to solve at least one of the above technical problems.
