摘要
无变换器不间断电源是一种不包括任何功率变换器的不间断电源,完全去掉了传统UPS中的所有变换器,只剩下静态开关、蓄电池及其充电控制器,大大提高不间断电源的安全性和可靠性,在保留所有必要特征的前提下,其成本、体积、重量、功耗是传统UPS的千分之一。整机对网侧无干扰,输入端功率因数为1,总谐波畸变THD为零。
Uninterrupted power supply without converter is a kind of UPS not including any power converter, removes completely all converters in traditional UPS, is only left over the static switch, the accumulator cell and its charge controller, enhances the UPS greatly the security and the reliability, at the premise that reserve all necessary characteristics, its cost, the volume, the weight, the power loss are all the 1/1000 of traditional UPS. Entire machine does not have the disturbance to the net side, the input end power factor is 1, total harmonic distortion THD is a zero.
