Description

technical field [0001] The present disclosure relates to a power converter, an inductance element, and an inductance cutting control method, and more particularly, relates to a power converter, an inductance element, and an inductor capable of improving the performance of the converter. Excision control method Background technique [0002] In recent years, with the development of data center, artificial intelligence and other technologies, the working speed of central processing unit (CPU), graphics processing unit (GPU) and various integrated chips (IC) is getting faster and faster, and the working current is getting bigger and bigger. , the power density, efficiency, dynamic performance and other aspects of the voltage regulation module (VRM) of its power supply module are becoming more and more stringent, which poses a very high challenge to the design of the VRM. In the voltage regulation module, the volume of the output inductor often accounts for the highest proportio...
