The present application discloses a dynamic optimization system of a polyphase coupled inductance voltage regulator, including a collection device, a processing device, and an energy release device arranged at the output end of the multiphase coupled inductance voltage regulator, wherein: the collection device is used to collect additional The current signal of the inductor, and output the voltage drop signal corresponding to the current signal; the processing device is used to determine the system operating state according to the voltage drop signal, and when the system operating state is from a heavy load to a light load state, a first trigger signal is generated; The energy device is used to release the energy generated when the system changes from heavy load to light load when the first trigger signal is received. The present application can release the excess energy generated when the heavy load is transferred to the light load, so as to avoid the overcharge of the output voltage of the polyphase coupled inductance voltage regulator and damage to the load.

Description

technical field [0001] The present application relates to the field of data centers, and in particular, to a dynamic optimization system for a polyphase coupled inductor voltage regulator. Background technique [0002] High-power integrated circuits used in data centers consume large amounts of energy, and currents fluctuate rapidly as data throughput fluctuates. At this stage, in order to meet the quality of output current and output voltage at the same time, it is necessary to add a large number of coupling capacitors on the load side. However, the current demand gradually increases, the area of ​​the existing board remains unchanged, and the traditional power supply method gradually shows its limitations. When there is a large change in the current, the output voltage itself will fluctuate greatly. [0003] In order to optimize the dynamic response rate of the traditional power supply scheme, the coupled inductors can be used to connect the output inductors in the high-...

AI Technical Summary

Problems solved by technology

Since the secondary coupling line is composed of inductors, there are no power consumption components. Therefore, when the load current changes from large to small, that is, when the system changes from heavy load to light load, the energy generated will cause the output voltage to surge, which poses a safety hazard.
