Problems solved by technology

[0004] The traditional perturbation and observation method is only applicable to the situation without shadows. When partial shadows appear on the photovoltaic array, the power output curve changes from single peak to multi-peak. At this time, the perturbation and observation method will cause misjudgment and cannot track the maximum power point.
