Description

technical field [0001] The invention relates to the technical field of electronic circuit control, in particular to a real-time energy consumption control technology for multi-phase parallel working mode power supply. Background technique [0002] With the continuous improvement of the performance of high-performance computing, data centers and large-scale industrial equipment, their power consumption has also increased significantly, and how to make them green and energy-saving has become more and more important. [0003] Existing energy management and control technologies are mostly used on the load side, that is, to configure the load working mode according to demand, but there is no energy consumption control technology for the power supply unit itself. In the effective load range of the power supply unit, the conversion efficiency of the low load area and the high load area is relatively low, which limits the performance index of the power supply unit to a large extent....
