摘要
阐述了一种小功率太阳能电池模拟装置。该模拟装置由AC-DC变换器与DC-DC变换器组成,AC-DC变换器将交流输入转换成直流电,DC-DC变换器将该直流电转换成具有太阳能电池输出特性的直流电。采用数字信号处理器MO-TOROLA56f801来控制.控制方法采用单极性SPWM法,模拟太阳能电池特性曲线采用三次样条插值算法。该控制方案已经在实验室得到验证,实际效果令人满意。
This paper presents design of low-power Digital PV Simulator. This simulator consists of a AC-DC convertor ,a DC-DC converter .The AC-DC convertor change the alternating current into derect current. The DC-DC convertor change the derect current into another derect current of the same characters with PV. This simulator is controlled by a MOTOROLA56f801 dsp control chip. This paper provide a control method of single polarity spwm ,and use the spline method to simulate the characters of the PV.The availability of this control system is verified,and it achieved a satisfying effect.
