Globality and logistic exploitation ask for matched systems to topologies [telecommunication power supplies]

With the change of the market toward globality, SYKO recognized in 1991 that various system topologies must be mastered to meet the functions and standards for customer-specific power supply solutions. They wish to provide the knowledge gained in the area of railroad technology and the globalization occurring there for the area of telecommunications also. This paper is intended to show how strategic advantages can be gained under the heading of “total cost of ownership” from new concepts designed and patented by their company. The system topology to be used depends primarily on the requirements of the specifications. The main parameters are: the input interfaces (i.e. AC/DC, industry, road-car, railway and aircraft) with limited or a very-wide-input-range, as well as the requirements for the output voltage, (unipolar, multiple, low- or high-voltage). The logistic advantages of the concepts demonstrated by us are obvious. With the demonstration of mastering multiple rated voltages and/or battery voltages 24/36/48/60/72/96/110/220 V DC plus 110/220 V AC with 16 2/3 and 50 Hz, the market responds by great interest and increasingly recognizes the logistic and market-specific advantages
