2チャネルMPPT機能を有するマルチパワーコンディショナ

抄録

We have developed a new power conditioner of solar energy system for residences. We have named it “the multi-dc input power conditioner” which equips dual input of photovoltaic arrays. One input called “standard input” connects to arrays which generate higher voltage than the other arrays, and another input called “multi-input” connects to arrays which generate lower voltage. The output voltage of arrays on the “multi-input” side is boosted up to the output voltage of arrays on the “standard input” side by the built-in boost converter. That circuitry enables to control MPPT for each array independently. Consequently, this new power conditionercan improve the efficiency of the system in the case of irregular configuration of photovoltaic modules on the roof.
