Abstract

Provided is a serial power supply circuit, characterized by comprising: a first power supply unit, the first power supply unit being connected in parallel and being used for providing a first power supply voltage; a second power supply unit, the second power supply unit being connected in series and being used for providing a second power supply voltage; a power source unit for providing the firstpower supply unit and the second power supply unit with a power supply voltage; and a unit to receive power, the unit to receive power being provided with a first power supply unit access end for receiving the power supply voltage provided by the first power supply unit. The present invention achieves the aim that the power source conversion efficiency thereof is obviously better than that of a traditional serial and parallel power supply architecture in the current industry, and same also reduces an overall power supply current of a circuit, further simplifies a power supply circuit, and saves on the material costs of a device.

Description

technical field [0001] The invention relates to power supply technology for integrated circuit chips, in particular to a series power supply circuit, system and method. Background technique [0002] With the continuous and rapid development of cloud computing and server-level large-scale computing, as well as the global awareness of environmental protection and energy conservation, energy efficiency has become a very important indicator in the hardware computing system. [0003] At present, computing equipment based on large-scale integrated circuits adopts the traditional parallel power supply architecture, which has obvious disadvantages such as excessive current and low energy efficiency, and increases the requirements for chip circuit design and the cost of production design. With the development of semiconductor technology, the working power supply voltage of the chip is getting lower and lower, and the working current is getting bigger and bigger. In order to maximize ...
