摘要

根据式(2)，采用BE电路的通信电源整流器分为7个等级，允许总输入电流谐波畸变小于60%、45%、35%和10%。可以连接到400v的2- 20jkva额定值要求在3- 25kva的线路输入电流下谐波畸变小于45%和35%。额定值高达50kva可能产生最大10%的谐波，或者必须连接到单独的中压变压器。

18 kW Switch Mode Rectifier Circuit Topology

According to (2), rectifiers for telecommunication power supplies with BE circuits are graded in 7 classes that permit total input current harmonic distortion of less 60%, 45%, 35% and 10%. The 2-20 JkVA ratings that can be connected to 400 V call for harmonic distortions less than 45% and 35% for the line input current at 3-25 kVA. Ratings up to 50 kVA may generate harmonics of 10% maximum or they must be connected to a separate medium-voltage transformer.
