| Abstract(in English) | In a DC power supply system, a rectifier consisting of multiple parallel converters transforms AC to DC. The efficiency of converter depends on converted power level so that there is a possibility to raise efficiency of the DC power supply system by adjusting converted power with each converter. In this paper, we propose a new rectifier control method which adjusts percentage of converted power by applying active power control for a part of multiple parallel converters. The effectiveness of the method is shown by electromagnetic transient analysis simulation. And also, in order to determine the optimum allocation of converted power to each converter, a maximization problem of DC power system efficiency is formulated as a nonlinear optimization one and the solution is developed. |
