Abstract
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 typically use hard-switching technology, which involves switching at high current and voltage. The primary problem with this technology is the high switching losses, which lead to low system efficiency. As switching frequencies increase, the high-frequency harmonics and electromagnetic interference (EMI) generated during hard-switching operations become increasingly serious, failing to meet the demands of efficient, low-loss energy conversion. Furthermore, high-frequency harmonics in the system can interfere with the normal operation of other electrical equipment, leading to increasingly prominent electromagnetic compatibility (EMC) issues. Furthermore, in the EMC design of traditional power supply control devices, EMI is typically reduced by adding shielding layers or filters. However, this passive shielding approach not only increases the size and cost of the device but also fails to achieve real-time control of dynamic EMI. In complex industrial applications, the dynamic changes in the electromagnetic environment often lead to unstable EMI. The anti-interference design of existing devices struggles to adapt to these changes, resulting in unstable system performance.
[0003] While high switching frequencies help reduce the size of electrical components and improve system response speed, they also present a more serious problem: electromagnetic interference. High-frequency harmonics generated by high-frequency switching can cause electromagnetic interference, disrupting other electrical components in the system and particularly adversely affecting adjacent signal transmission lines, sensors, and other sensitive devices. This situation is particularly common in consumer electronics, communication base stations, and industrial automation equipment, and in severe cases, can even cause equipment failure or malfunction.
