Abstract
En 中文
The goal of the present study is to develop a photovoltaic generation system for small-scale air conditioners. The structure of the photovoltaic generation system comprises an intelligent maximum power point tracking controller, a bidirectional DC-DC converter, and a small-scale air conditioner, wherein the intelligent maximum power point tracking controller adopts the extension perturb and observe method, such that the controller excels at dynamic response and achieves a stable performance. Since the maximum power point tracking process results in variation in the voltage of the DC-link, the present study proposes a DC-link voltage regulation strategy. This system makes use of the bidirectional DC-DC converter and the charge/discharge control of the battery to achieve DC-link voltage regulation, and uses the regulated stable voltage of the DC-link to supply power for the small-scale air conditioner. Finally, the practicality of application of the photovoltaic generation system in small-scale air conditioners is verified with evidence based on simulation and empirical testing.
