  author={Reinhard Enne and Miodrag Nikolic and Horst Zimmermann},
  journal={IEEE Transactions on Power Electronics},
An integrated CMOS controller with fast maximum power point regulation for module-integrated automotive solar converters with nine solar cells per string is reported. It provides the 530-kHz switching signals for the module-integrated converter whereby the mean output current of the module is maximized. The on-chip “perturb and observe” algorithm bases on a quasi-analog principle and performs more than 1000 tracking cycles/s at a power consumption around 560 μW. In order to maximize the… CONTINUE READING
