The per-unit system base for this power system is 40 MVA, 128 kV in transmission line 1. Create the per-phase, per-unit equivalent circuit for this power system. SOLUTION This power system has been divided into regions at the transformers, with the base voltage and apparent power specified in Region 2 to be 128 kV and 40 MVA.
The DSL power system may supply both higher voltage analog line drivers and amplifiers (typ. +/-12V) and several low voltage supplies required by the digital ASIC (+5V, +3.3V, +1.8V, +1.5V).
In a 3G Base Station application, two converters are used to provide the +27V distribution bus voltage during normal conditions and power outages.
A preferred power supply architecture for DSL applications is illustrated in Fig. 2. A push-pull converter is used to convert the 48V input voltage to +/-12V and to provide electrical isolation. Synchronous buck converters powered off of the +12V rail generate various low-voltage outputs.
