Problems solved by technology

[0002] At present, the bitcoin mining machines on the market are basically parallel mining machines using DC / DC (direct current to direct current) chips. Due to the low conversion efficiency of DC / DC, the power supply energy is wasted. At the same time, DC / DC The circuit design of the circuit is relatively harsh, which will increase the design requirements and increase the cost of production design

Abstract

The embodiment of the invention discloses a power supply circuit, and relates to the technical field of power supply, wherein the power supply circuit comprises an adjusting unit and a plurality of packaging units; the plurality of packaging units are connected between a power supply end and the ground in series; each packaging unit comprises one or more sets of components; each set of components comprises a connected chip to be powered and an auxiliary power supply unit; a signal level conversion unit is respectively connected between the chips to be powered in two sets of adjacent components in series; various chips to be powered are respectively connected to the adjusting unit; the adjusting unit performs temperature or frequency adjustment of the various chips to be powered according to the working states of the various chips to be powered; and thus, all the chips to be powered in the power supply circuit are in a normal working state. By means of the embodiment of the invention, the design production cost can be reduced; the problem of low power supply energy conversion efficiency can be effectively overcome; furthermore, the volume of a PCB also can be reduced; and thus, the working voltage of the various chips to be powered is balanced.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a power supply circuit. Background technique [0002] At present, the bitcoin mining machines on the market are basically parallel mining machines using DC / DC (direct current to direct current) chips. Due to the low conversion efficiency of DC / DC, the power supply energy is wasted. At the same time, DC / DC The circuit design of the circuit is relatively harsh, which will increase the design requirements and increase the cost of production design. [0003] Therefore, a technical problem that needs to be solved urgently by those skilled in the art is: how to innovatively propose an effective measure to meet more demands in practical applications. Contents of the invention [0004] The technical problem to be solved by the embodiments of the present invention is to provide a power supply circuit, a virtual digital coin mining machine and a computer server. [0005] In order ...
