Performance Improvement of a DC-DC Converter Feeding a Telecommunication Specific Distributed Power System Using Dynamic Decoupling Design


This work analyzes the stability of a distributed dc power system commonly used in telecommunication and data center applications and proposes a new design procedure based on dynamic decoupling of the effects of the downstream network on the upstream source converter. First, the small-signal model of the upstream converter is introduced. Next, the model of the downstream network is added to the converter model and the complete system model is extracted. Then, the loop gain of the upstream converter when it is feeding the downstream network and when it is feeding a single resistor is compared and the decoupling factor is found. Finally, simulation results are provided to verify the design procedure.
