太陽能光電板在受到部分遮蔽時,有熱點及輸出功率降低的問題。為減緩這些問題,便以反平行方向連接旁路二極體。然而,增加旁路二極體影響到太陽能光電板的發電特性,使之產生多個高峰。因此,在部分遮蔽下,使用傳統軟體型最大功率追蹤器(MPPT)來追蹤最大功率輸出點變得十分困難。電流-電壓特性曲線掃描器透過掃描多個可能的最大功率點(MPP)區域,可協助軟體型的 MPPT尋找真正的最大功率點。
因此,電流-電壓曲線掃描器搭配軟體型的MPPT較受青睞。在此針對幾種電流-電壓曲線掃描器的優劣進行調查,並透過將磁滯自控責任週期調變之負載電阻 (DMLR)應用在升壓轉換器型電流-電壓曲線追跡器上,提出負載自適型太陽能板特性曲線掃描器。此掃描器有以下幾項優勢,如結構簡單、低實踐成本、及在Voc附近無掃描限制等。在此亦模擬且實作出一個120W 的太陽能光電板,以便實證所提出的曲線掃描器之可行性。
Photovoltaic (PV) panels are subject to problems such as hot spots and reduced output power when operating in partially shaded conditions. Although bypass diodes are utilized to alleviate these problems, the diodes cause multiple-peak characteristics. Tracking the maximum output power point in partially shaded conditions is difficult using conventional software-based maximum power point tracking (MPPT) techniques. Current-voltage (I-V) curve tracers can assist software-based MPPT to track the true maximum power point (MPP) by scanning several potential MPP areas.
Therefore, a software-based MPPT with an I-V curve tracer is a preferred solution. This study investigates the advantages and disadvantages of several I-V curve tracers and proposes a load self-adaptive PV panel characteristic curve tracer by applying a hysteretic self-controlled duty-modulated load resistor (DMLR) to a boost converter I-V curve tracer. Several advantages are achieved, such as simple structure, cost-efficient implementation, and no tracing limitation near the Voc. A circuit for a 120 W PV panel is simulated and implemented to verify the feasibility of the proposed curve tracer.
