从最严格的意义上来说,不存在计算机用的不间断交流电源。 交流电源系统中,电源特性取决于负载特点。计算机是一种特殊的负载,它以8.3毫秒为周期或者说以每秒120次的脉冲形式消耗电能。实际上计算机工作时,电源的整流器使计算机电源在将近70％的时间里不供电。所以认为计算机需要电源不停地连续供电的观点是错误的,因为实际上电源每秒钟被中断了120次。就计算机以脉冲形式消耗电能方面来说,可以认为不存在计算机用的不间断电源。 为了进一步阐明这一观点,我们对一台典型的Compaq 386配置的微机电源进行测试。一艘来说,测试结果应用瓦特、伏特、安培值来表示,但这些值是一
In the strictest sense, there is no uninterrupted AC power for computers. In AC power systems, the power characteristics depend on the load characteristics. The computer is a special load that consumes power in the form of pulses of 8.3 milliseconds or 120 pulses per second. In fact, when the computer is working, the power rectifier does not power the computer for nearly 70% of the time. Therefore, it is a mistake to assume that computers need a continuous supply of power continuously because the power is actually interrupted 120 times per second. In terms of computer power consumption in terms of pulses, it can be assumed that there is no uninterruptible power supply for computers. To further clarify this view, we tested the microcomputer power of a typical Compaq 386 configuration. A ship, the test results using watts, volts, amperes to represent, but these values ?? are
