Description

server

The present invention relates to a server, and more particularly to a server that can reduce the power consumption of a power source and improve the working efficiency of the power source.

Over the years, with the advancement of electronic technology, people's requirements for electronic related products have also increased. In order to provide people with high quality and low price, how to effectively save the volume of electronic products has become an important issue for today's electronic product designers. Since in general electronic devices, multiple sets of power supplies are required to provide the operating voltage, in order to avoid the use of a plurality of bulky transformers to provide these different voltages, the power supply has become a power supply device that designers have paid attention to. .

For example, many integrated circuit chips located in the server need to start operating in the system standby state, so it is necessary to pass through the power supply to generate several DC voltages as required for the voltage of these integrated circuit chips. Once the system is powered on, the system will switch to the working state, and the DC voltage to the working state will be used. However, in addition to using the DC voltage to the operating state, the system also uses the DC voltage to the standby state.

In general, most of the power supplies used in the prior art do not have the function of voltage switching, so that the servo uses the working voltage and the standby voltage simultaneously in the working state, resulting in unnecessary power consumption of the power supply, and also reducing the power supply. Work efficiency.

The invention provides a server, thereby reducing the power consumption of the power source and improving the working efficiency of the power source.

According to an embodiment of the invention, a server has a standby state and a working state, and the server includes a power module, a detecting circuit, a switching circuit, at least one first electronic component, and at least a second Electronic component. The power module is configured to provide a standby voltage corresponding to the standby state and an operating voltage corresponding to the operating state. The detecting circuit is coupled to the power module for receiving a working status signal of the server, and generating a control signal according to a level of the working state signal. The working status signal is used to indicate that the server is in a standby state or a working state. The switching circuit is coupled to the detecting circuit and the power module for receiving the converted control signal, the working voltage and the standby voltage, and selecting the output working voltage or the standby voltage according to the converted control signal. The at least one first electronic component is coupled to the switching circuit for operating in an active state and not operating in a standby state. The at least one second electronic component is coupled to the switching circuit for operating in a standby state and an operating state. Wherein, when the server is in the standby state, the switching circuit selects the output standby voltage to the second electronic component according to the converted control signal, and when the server is in the working state, the switching circuit selects the output working voltage according to the converted control signal. The first electronic component and the second electronic component are given.

The server provided by the present invention firstly generates a control signal by receiving a working state signal by the detecting circuit, and receives the converted control signal by the switching circuit, and selects the output working voltage according to the converted control signal or Standby voltage. In this way, the power consumption of the power supply can be effectively reduced and the working efficiency of the power supply can be improved.
