Description
technical field [0001] The invention relates to the field of inductance, in particular to a high-current inductance for fast multi-phase voltage adjustment. Background technique [0002] Since the transient response in the traditional circuit depends on the capacitor bank of the circuit output, and the output filter inductance prevents the rapid rise from the voltage regulator, and these polymer capacitors usually have the risk of life degradation during use; However, based on the structure of the existing high-current inductors, after long-term use, the inductors are prone to aging, increased resistance, decreased magnetic permeability, increased eddy current loss, and susceptibility to interference. [0003] In order to solve the above problems, this application proposes a high-current inductor for fast multi-phase voltage adjustment. Contents of the invention [0004] (1) Purpose of the invention [0005] In order to solve the technical problems existing in the backgr...
