论传统不间断电源即将“功成身退”

Demonstrate the Traditional UPS about to Retire after his Meritorious Service

传统UPS包括一个或多个功率变换器,输出的是交流电压,对用户设备有谐波干扰;复杂的保护电路,连自身也保护不了,故障率太高,并且,体积庞大、效率低,浪费了太多的能源、资源、人力,已到更新换代的时候了。UPS的用户设备都广泛使用了高可靠、高效率的开关电源,直流电压可以直接进入用户设备,UPS把直流逆变成交流,已无必要。因此,功率变换器在UPS中已是多余。直流UPS免除了传统UPS中的功率变换器,安全、可靠、节能、环保、无干扰、寿命长,在保持所有必要特征的前提下,成本、体积、重量、功耗都是传统UPS的十分之一,百分之一,乃至千分之一,是传统UPS的换代产品。

the traditional UPS including one or more power converters,the output is the alternating voltage,has the harmonic interference to the consumer＇s equipment;The complex protection circuit, also could not protect including oneself, the failure rate too was high; At the same time volume huge, the efficiency was low, has wasted too many the energy, the resources, and the manpower, it is already to the renewal time. The consumer＇s equipment of UPS all widely used the high reliable, high efficiency switching power supply, so the DC voltage may enter the consumer＇s equipment directly, the UPS inverted the DC to AC, has not had the necessity, therefore, the power converter in the UPS already was unnecessary. The DC UPS gets rid of the power converter in the traditional UPS, the security,reliable, the energy conservation, the environmental protection,does not have the disturbance, the lifeyime is long,in under the maintenance all essential characteristics premise, the cost, the volume, the weight, the power loss all is 1,/10,1/100,and even 1/1,000 of the traditional UPS, so it is the update product of the traditional UPS.
