컨버터의 출력전압 리플 저감을 위한 새로운 병렬운전 방법에 대한 연구 = A Novel Paralleling Method of Converters for Reduction of Ripple in Output Voltage

다국어 초록 (Multilingual Abstract)

For the paralleled operation of DC/DC converters, the current sharing between each modules is the most important for the reliability of the power system. Interleaving method is commonly used with many paralleling schemes for the reduction of the ripple in the output voltage of paralleled converters and there are many commercial IC for interleaving application appliable. But for all of them, it is impossible to detect the number of module in operating and then change the phase of them automatically.
In this paper, a novel paralleling method is proposed for the converter parallel operation which detects the number of modules in active and sets the phases of PWM signals applied to each modules automatically. This can greatly improve the output voltage ripple and reliability of the system. The expandibility of modular number can be done very easily by just adding several parts.
