Voltage following series power supply circuit

Abstract

The invention relates to a voltage following series power supply circuit. The circuit comprises a power supply terminal, a ground terminal, a power supply module and at least one auxiliary power supply module, wherein the power supply module comprises an input terminal and an output terminal, the input terminal is connected to the power supply terminal, and the output terminal is used for supplying a power supply to two or more to-be-powered-up chips; the power supply module and the to-be-powered-up chips are connected in series between the power supply terminal and the ground terminal; the atleast one auxiliary power supply module is used for providing auxiliary power supplies for the to-be-powered-up chips; a voltage following module is also connected between the power supply terminal and the at least one auxiliary power supply module and used for adjusting the voltage of the auxiliary power supplies.

Description

Technical field

[0001] The invention relates to a series power supply circuit, in particular to a series power supply circuit capable of realizing voltage following. Background technique

[0002] For computing devices that require a large number of high-speed operations, such as current Bitcoin mining machines, multiple computing power chips are connected in series on a printed circuit board, and most computing power chips use a series power supply mode. When the series power supply mode is adopted, the power of each level of computing power chip can be regarded as the ground of the previous level of computing power chip, and the ground of each level of computing power chip can be regarded as the power of the next level of computing power chip.

[0003] Since the power and ground voltages of each level of computing power chips are different, how to supply power to the IO of this level of chips has become a more difficult problem. For the subsequent cascaded computing power chips, ...

[0051] The structural principle and working principle of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0052] Certain words are used in the description and subsequent claims to refer to specific components. Those with general knowledge in the field should understand that manufacturers may use different terms to refer to the same component. This specification and subsequent claims do not use differences in names as a way to distinguish components, but use differences in functions of components as a criterion. Throughout the specification, the same reference numerals denote the same elements.

[0053] The "including" and "including" mentioned in the entire specification and the subsequent claims are open-ended terms and should be interpreted as "including but not limited to". In addition, the term "connection" here includes any direct and indirect electrical connection means. Indirect electrical connection means include co...
