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, a virtual digital currency mining machine and a computer server, and relates to the technical field of power supply. The power supply circuit is characterized in that a plurality of packaging units are connected in series between a power supply end and the ground; each packaging unit comprises one or more groups of elements; each group of elements comprises a chip to be supplied with power and an auxiliary power supply unit which are connected with each other; and a signal level conversion unit is connected in series between the chips to be supplied with power in two groups of adjacent elements. Through adoption of the power supply circuit, the virtual digital currency mining machine and the computer server, the design and production cost can be lowered; the problem of low power energy conversion efficiency is solved effectively; and the PCB (Printed Circuit Board) size can be reduced.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a power supply circuit, a virtual digital coin mining machine and a computer server. 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 c...
