Resonant Analysis of Load Commutated Current Source Inverter System

부하(負荷) 전류식(轉流式) 전류형(電流形) 인버터 시스템의 공진(共振) 해석(解析)

At LCCSI system, output capacitor of inverter and inductor of load motor raise mutuality operation. This parallel resonant increase equivalent impedance of inverter load and give wrong effect at LCCSI system. This paper carried out resonant analysis of LCCSI system. The result of analysis, particular resonant point of two was discovered that a resonant of S=0 vicinity and $\beta$ resonant of S=1 vicinity. In addition to, the case of harmonics resonant not come from $\alpha$ resonant but come from $\beta$ resonant. A moment of working of LCCSI system, resonant line must not suddenly variation. Accordingly, resonant line is a necessity for doing $f{\alpha}$ vicinity by properly capacitor value selection.
