太陽光発電システムのための電力平衡に基づく最大電力点追尾制御方式

系の安定性と応答性に着目した設計法

抄録

Authors previously proposed a new MPPT control scheme for PV system connected in parallel with the ac system line. The system needs no sensors or calculation for PV array power detection, but utilizes an interior control signal of dc link voltage control loop itself. For this reason, system response and stability greatly depend on the main circuit and control system parameters. This paper shows system design based on stability analysis. Response of the experimental system has been proved fast enough for practical use.
