【正文】 process, it controls the solar plate of battery charging, speed up the battery charging, prolong the service life of the battery. Solar charge controller but also control the load power supply, battery protect battery and load circuit, avoid battery discharge phenomenon, thus, the controller plays a decisive role.City currently has a variety of solar controller, but the main problem controller to protect the battery enough, inappropriate is easy to cause the damage to the battery charge and discharge way, reduce the service life of the battery. At present, the monly used controller battery charging method includes three types: constant current charging method, phase charging method and constant voltage charging method. But these methods due to the imperfection of the charging ways of a single and control strategy, there are some limitations. On the other hand, when the battery to the load power supply, as the battery voltage detection controller can39。Khadaro 附件2：外文原文 SOLAR POWER GENERATION TECHNOLOGY —— Photovoltaic power generation system controller B (6)電流指示器 ：模擬或數(shù)字方式顯示太陽電池方陣電流 和輸出的負載電流。當蓄電池處于低 的荷電狀態(tài) 時，啟動后備電源，例如柴油發(fā)電機向蓄電池組充電。當充電電壓達到予置電平時 ，充電脈沖寬度變?yōu)榱?，充 電終止。 2．3 多階控制器 多階控制器依據(jù)蓄電池的充電狀態(tài)，自動設(shè)定不同的充電電流。二極管的作用如同一種形式的閥門，充電期間允許電流流入蓄電池 ，在夜間防止蓄電池電流向方陣“回流”或稱“反向泄漏”。所以，如何改善太陽充控制器的充放電方式，開發(fā)性能優(yōu)良的充放電控制器，提高其在實際應用中的效率，成為了一個重要的研究方面。在進行太陽能光伏發(fā)電時，由于一般太陽能極板輸出電壓不穩(wěn)定，不能直接將太陽能極板應用于負載，需要將太陽能轉(zhuǎn)變?yōu)殡娔芎蟠鎯Φ揭欢ǖ膬δ茉O(shè)備中，如鉛酸蓄電池。MauritiusUniversityJ同時太陽能充放電控制器還控制蓄電池對負載的供電，保護蓄電池和負載電路，避免蓄電池發(fā)生過放現(xiàn)象，由此可見，控制器具有舉足輕重的作用。 旁路控制器 旁路控制器主要用 于小型光伏 系 統(tǒng)。分流控制的缺點是，有限的負載操作能力和有通風要求 2．2 串聯(lián)控 制 器 當蓄電池電壓達到被稱為充電終止點的予置電壓值時，串聯(lián)控制器通過開關(guān)切斷電流 ，防止蓄電池過充。當蓄電池組漫漫接近完全充滿時 ，“涓流”充電漸漸停止。如果不注意 ，光伏系統(tǒng)的負載能夠輕易地耗盡蓄電池的電 能。 (1)溫度補償：依據(jù)環(huán)境溫度調(diào)整蓄電池充電電流。 (9)方陣功率分流調(diào)節(jié)器：將多余的方陣充電功率旁路到 非重要負載 ，例如電熱水器等。t time, so it is easy to occur over discharge of battery, will lead to the depth of the battery discharge, seriously affect its life.So, how to improve the solar charge controller to charge and discharge, development of excellent performance of charge and discharge controller, to improve the efficiency in the practical application, has bee an important research aspect.Two types of controllerThe basic function of the controller is similar to the voltage regulator, is mainly used to prevent the battery by solar elect
