TWI284797B - Power supply unit having displaying operation status function of individual loading power - Google Patents

Abstract

The present invention relates to a power supply unit having displaying operation status function of individual loading power. A power detection device is disposed on a power supply circuit of each set of DC output power supply between a secondary rectification of voltage-stabilized circuit and post loads of the power supply unit in the present invention; the power detection device makes the DC output power supply generate power variation and connects circuit to a power conversion unit to generate a power detection value; the power detection value is outputted to a loading power display unit, and the corresponding operating power values of each set of output power supply can thus be displayed; if one load thereof is a reference ground, the total power value of the DC output power supply during operating state can be displayed.

1284797 IX. Description of invention: [Technical field to which the invention belongs], and the secrets of the county--------------------------------------------------------------------------------------------------------------------------------------------- The basic palm of the vacancies (4) is rarely used in the Wei dynasty, especially in response to the Internet and multimedia technology. _ Under the power supply piracy, the effective supply power must be immediately available to the user. Hunting to avoid the long-term heavy load or overload of the power supply caused by the temporary ^ computer syllabus (10) into a work interruption or the document of the Republic of China Announcement Patent No. M258494 and the document No. M26_ shows the use of power state technology to M258494 For example, the f'"-linear rectification circuit is integrated into the power supply of the power supply unit. The total combined power in the use state is large == is the host; te b " ̄ effect control, the main reason is Many high-power load (especially makeup can be ^ board; ^ central, 1 will map card, etc.) if long-term heavy load or overload power i generate life! = condition, especially the power supply of its - DC Output] This, how can I target individual DC The effective monitoring of the output power supply becomes == Lesson [Invention content] The main purpose of the discussion is to solve the above-mentioned shortcomings and avoid the lack of defects in the ^, "==== power supply state of the output power supply to solve the problem, ' The load power display unit shows the use of each group of DC output power 0 (Ά 5 1284797. Judah prompts that the financial dislocation should be (9) if the inspection is not buried, too niff aging, or even need to consider replacing the power supply, etc. ), and the invention can be used to control the power consumption of the computer system, so that the risk of damage caused by power transmission is effectively reduced. The above is only a preferred implementation of the present invention. The scope of the present invention is not limited to the scope of the present invention. The equivalent variations and modifications of the scope of the patent application of the present invention should be the technical scope of the present invention. 1284797 [Simple Description] 1 is a schematic diagram of a circuit block diagram of the present invention.
