The invention discloses an intelligent component optimizer for a solar photovoltaic
cell panel and a control method thereof. A controller for the component optimizer in a component
optimization system uses a high-performance high-speed DSP (
digital signal processor) as a core, and a high-frequency direct-current
switching power supply technology is introduced in a distributed
photovoltaic power generation system, direct-current conversion topology for
voltage increase or
voltage reduction can be selected according to a direct-current conversion adjustment margin, and the working mode of the component optimizer can be selected by a control method of observing a pre-stage input
voltage, a pre-stage input current, a post-stage output voltage and a post-stage output current in real time, so that the components of the photovoltaic
cell panel cannot generate a mismatching phenomenon in the case of any
irradiance; simultaneously, each component can have the maximum
power output, thus greatly gaining the electric quantity of a photovoltaic
cell array, which is lost due to non-uniform
irradiance, so that the power generation
utilization rate of the whole photovoltaic cell array is optimal. The component optimizer and the control method have good application prospect.
