Stability Comparison of Three Control Schemes for Bus Converter in Distributed Power System

Recently, the distributed power system consists of bus converter and POL is usually used for IT infrastructure equipment. The system may become unstable depending on the bus converter design even if each converter has stable operation. Then, the bus voltage is oscillated. Recently, stability problems in distributed power system become series. It is required to overcome these problems as soon as possible. This paper investigates, the improvement of the system stability by the control method. As a result, the full-regulated bus converter is the best as a control method of the bus converter because the full-regulated bus converter can reduce the bus voltage oscillation and correspond to the input voltage variation flexible by the regulation.
