微功耗不间断电源

Microloss Uninterruptible Power Supply

微功耗不间断电源采用整流升压器和微分逆变器,实现了不间断电源的全部功率。该微功耗不间断电源的最大特点是,只要把输入功率中极小部份进行功率变换,就可以得到全部输出功率,即输入功率中极大部份既不必进行实际的功率变换,也不必通过磁芯变压器或电感传递,直接到达输出端,成为输出功率,主功率器件工作在工频,不产生EMI干扰,电路简单,因此功耗极小而寿命极长,成本、体积、重量、功耗都是传统冰间断电源的十分之一。

The rectifying boost and differential inverter are applied to achieve UPS＇s total power, whose most distinguishing characteristic is taking a small portion of input power through power conversion process to obtain the total output power. That is, most portion of input power could connect to output terminal directly and become output power neither through power conversion process, nor through linear transformer or inductor transmission process. The main power devices are operating in fiequency, without EMI interference and with simple circuit, therefore its power consumption is very low while its lifetime can be extremely long. Its cost, size, weight and power consumption are one-tenth of the traditional UPS＇s.
