Abstract

To obtain the maximum power drew from the photovoltaic (PV) array as well as to control small power PV systems more easily and conveniently, a novel analog voltage-based maximum power point tracking control IC was proposed in this paper. Not only is the IC involved in tracking the maximum power point (MPP) of the PV array, but it also renews the value of MPP voltage each interval to detect the real-time output voltage of PV panel. The chip was designed and implemented in 1.5 mum BCD technology. The simulation results showed that the dynamic response time to impulse of either temperature or solar radiation strength was less than 2 ms and the static settling time was about 3 ms with 0.05% ripples.
