The corresponding output voltage, current, and power curves
of the PV module in the PV-DCBM are shown in Fig. 15.
Fig. 15(a) shows the start process and the step decrease of illumination level, while Fig. 15(b) shows the start process and the
step increase of illumination level. It can be seen that the start
process is smooth, and takes about 3.6 s. The ACCFHBC can
