技术领域 technical field
本发明为一种电源供应调整方法，尤指应用于一计算机系统与一多相电源供应器的电源供应调整方法。The present invention is a power supply adjustment method, especially a power supply adjustment method applied to a computer system and a multi-phase power supply.
背景技术 Background technique
在目前的计算机系统中，利用多相电源供应器来提供系统所需的电力已是常见的手段，主要是利用多个电力转换单元来组合出一个整体效率较佳的多相电源供应器，其目的是用以解决单一电力转换单元处于高负载状态下效率偏低的问题。但是，系统并非一直处于高负载状态，例如，计算机系统中的显示卡并非一直处于需要消耗大电流的3D影像处理模式，而是大部分处于一般耗电量的2D影像处理模式。而多个电力转换单元的多相电源供应器运作在低负载状态时并非一定效率较佳，反而有可能造成效率不佳的问题。In current computer systems, it is common to use multi-phase power supplies to provide the power required by the system. The main method is to use multiple power conversion units to combine a multi-phase power supply with better overall efficiency. The purpose is to solve the problem of low efficiency of a single power conversion unit under a high load state. However, the system is not always in a high load state. For example, the display card in the computer system is not always in the 3D image processing mode that consumes a large amount of current, but mostly in the 2D image processing mode that consumes general power. However, when the multi-phase power supply with multiple power conversion units operates in a low-load state, it does not necessarily have better efficiency, but may cause a problem of poor efficiency.

具体实施方式 Detailed ways
请参见图1，其是可应用本发明方法的一计算机系统功能方块示意图，主要包含有一计算机系统10以及一多相电源供应器11，其中多相电源供应器11是根据计算机系统10的工作状态而供应适当的输出电流给计算机系统10使用。而本发明的多相电源供应器11中包含有多个可独立开启关闭的电力转换单元111-11n，因此电力转换单元111-11n是可接受计算机系统10的控制而改变其被启用的数量，进而改变多相电源供应器11的电源转换效率。Please refer to FIG. 1 , which is a functional block diagram of a computer system to which the method of the present invention can be applied. And supply appropriate output current to the computer system 10 for use. However, the
请参见图2，其是本发明所发展出来的电源供应调整方法的第一较佳实施例步骤流程示意图。首先，计算机系统10每隔一预定时间(步骤S20)便侦测该多相电源供应器11供应至该计算机系统10的一输出电流Io的大小(步骤S21)，然后根据该输出电流Io的数值变化而调整启用该多相电源供应器11中多个电力转换单元111-11n的数量(步骤S22)，进而动态调整多相电源供应器11而达到电源转换效率最佳化的目的。Please refer to FIG. 2 , which is a schematic flowchart of the first preferred embodiment of the power supply adjustment method developed in the present invention. First, the computer system 10 detects the magnitude of an output current Io supplied by the
再请参见图3(a)，其是以两个电力转换单元所完成的多相电源供应器为例所测量出来的输出电流与效率对应曲线图，其中所绘出的两条曲线分别代表单一电力转换单元启用(以下简称单相模式)及两个电力转换单元皆启用(以下简称双相模式)的输出电流与效率对应曲线，而由图可清楚看出，在高负载的高输出电流区中，双相模式的效率确实较单相模式的效率为佳，但是在低负载的低输出电流区中，则是单相模式的效率较佳。而由此例可观察出，两曲线约在10安培处交错，因此，当计算机系统10侦测到输出电流的数值大于或等于门坎值10安培时，便将多相电源供应器操作于双相模式，反之，当计算机系统10侦测到输出电流的数值小于门坎值10安培时，便将多相电源供应器操作于单相模式，如此将有效将电源转换效率最佳化，进而达到省能的功效。Please refer to Fig. 3(a) again, which is a graph corresponding to output current and efficiency measured by taking a multi-phase power supply completed by two power conversion units as an example, where the two curves drawn represent a single The corresponding curves of output current and efficiency when the power conversion unit is activated (hereinafter referred to as single-phase mode) and both power conversion units are activated (hereinafter referred to as dual-phase mode), and it can be clearly seen from the figure that in the high-load high output current area Among them, the efficiency of the dual-phase mode is indeed better than that of the single-phase mode, but in the low-load low output current region, the efficiency of the single-phase mode is better. It can be observed from this example that the two curves intersect at about 10 amperes. Therefore, when the computer system 10 detects that the value of the output current is greater than or equal to the threshold value of 10 amperes, the multi-phase power supply will be operated in two-phase mode, on the contrary, when the computer system 10 detects that the value of the output current is less than the threshold value of 10 amperes, it will operate the multi-phase power supply in single-phase mode, which will effectively optimize the power conversion efficiency and achieve energy saving effect.
再请参见图3(b)，其是以三个电力转换单元所完成的多相电源供应器为例所测量出来的输出电流与效率对应曲线图，其中所绘出的三条曲线是分别代表单一电力转换单元启用(以下简称单相模式)、两个电力转换单元启用(以下简称双相模式)及三个电力转换单元皆启用(以下简称三相模式)的输出电流与效率对应曲线，由图可清楚看出三条曲线所产生的两个交错点P1与P2所对应出的第一电流门坎值I1与第二电流门坎值I2，可以将输出电流分成三区：高输出电流区、中输出电流区以及低输出电流区。因此，当计算机系统10侦测到输出电流的数值大于或等于第二电流门坎值I2时，便将多相电源供应器操作于三相模式，而当计算机系统10侦测到输出电流的数值小于第二电流门坎值I2但大于或等于第一电流门坎值I1时，便将多相电源供应器操作于双相模式，至于当计算机系统10侦测到输出电流的数值小于第一电流门坎值I1时，便将多相电源供应器操作于单相模式，如此也可有效地将三个电力转换单元所完成的多相电源供应器的电源转换效率完成最佳化，进而达到省能的功效。依此类推，四个甚或更多个电力转换单元所完成的多相电源供应器也可用上述方法来进行最佳化，因此不再予以赘述。Please refer to Fig. 3(b) again, which is a graph corresponding to output current and efficiency measured by taking a multi-phase power supply completed by three power conversion units as an example, where the three curves drawn represent a single The corresponding curves of output current and efficiency when the power conversion unit is enabled (hereinafter referred to as single-phase mode), when two power conversion units are enabled (hereinafter referred to as dual-phase mode) and when all three power conversion units are enabled (hereinafter referred to as three-phase mode), are shown in Fig. It can be clearly seen that the first current threshold value I1 and the second current threshold value I2 corresponding to the two intersecting points P1 and P2 generated by the three curves can divide the output current into three areas: high output current area, medium output current area region and the low output current region. Therefore, when the computer system 10 detects that the value of the output current is greater than or equal to the second current threshold value I2, it will operate the multi-phase power supply in the three-phase mode, and when the computer system 10 detects that the value of the output current is less than When the second current threshold value I2 is greater than or equal to the first current threshold value I1, the multi-phase power supply is operated in a bi-phase mode, and when the computer system 10 detects that the value of the output current is less than the first current threshold value I1 When the multi-phase power supply is operated in a single-phase mode, the power conversion efficiency of the multi-phase power supply completed by the three power conversion units can be effectively optimized to achieve energy saving. By analogy, the multi-phase power supply completed by four or even more power conversion units can also be optimized by the above method, so it will not be repeated here.
另外，除了侦测该多相电源供应器11供应至该计算机系统10的输出电流Io来进行模式切换的判断外，还可以利用对计算机系统10本身各种负载状态的侦测，进而作出模式切换的判断。举例来说，图4是本发明所发展出来的电源供应调整方法的第二较佳实施例步骤流程示意图，首先，计算机系统10每隔一预定时间(步骤S40)便自动侦测自身的显示卡所处的影像处理模式(步骤S41)，例如是处于需要消耗大电流的3D影像处理模式，或是处于一般耗电量的2D影像处理模式，然后根据影像处理模式的变化而调整启用该多相电源供应器11中多个电力转换单元111-11n的数量(步骤S42)，进而动态调整多相电源供应器11而达到电源转换效率最佳化的目的。当然，除了影像处理模式外，还有其它模式也会与负载状态的大小相关，例如中央处理单元的电源状态(power state)等等，都可以拿来当作耗能大小的参考，进而来调整启用该多相电源供应器11中多个电力转换单元111-11n的数量。再举个例子，假如电力转换单元的数量为8，而中央处理单元的电源状态(power state)被分为4种，那便可以将多相电源供应器11分成为开启2个、4个、6个及8个电力转换单元等四个模式，用以对应至中央处理单元的4种电源状态(power state)，如此将也可让电源转换效率较为接近最佳化结果，进而改善上述技术手段的缺点，达成发展本发明的主要目的。In addition, in addition to detecting the output current Io supplied by the
故本发明不仅于技术思想上确属创新，并具备已知的传统方法所不及的上述多项功效，已充分符合新颖性及创造性的法定发明专利条件，故依法提出申请。然本发明由熟习此技术的人士可作些许的更动与润饰，然皆不脱离本发明的权利要求保护范围。Therefore, the present invention is not only truly innovative in terms of technical ideas, but also has the above-mentioned multiple functions that the known traditional methods cannot match. However, the present invention can be slightly changed and modified by those skilled in this technology, but all do not depart from the protection scope of the claims of the present invention.
