The new generation of MC controlled switched mode rectifier for telecom

The authors describe the new generation of Siemens microcomputer-controlled charging rectifiers, comprising a 30 A and a 100 A model. The nominal output voltage can be switched between 48 V and 60 V. For initial charging 84 V and a current that can be varied from 10%-100% * I_nom are available. As the power section is still the most up-to-date in this field, the first-generation power section with just a few minor changes could be used for the 100 A model. Because of the lower power, the power section was redimensioned for the 30 A model. The design is modular and all control modules are suitable for use in both models
