摘要
本文介绍了工频机与高频机UPS的主电路结构,指出了工频变压器的基本功能是变压和产生零点,并不抗干扰和缓冲。并介绍了电子变压器的优点,指出了高频机最终要代替工频机的必然趋势。
The paper introduced the UPS main circuits of the industrial frequency and high frequency. Pointed out industrial frequency transformer functions are converting voltage and producing nature point and it cannot avoid interferes or is not buffer. Introducing the benefits of electronic transformer and pointing out the direction of high frequency UPS replace industrial frequency one.
