Abstract
Description
図1は、従来用いられていた直流点灯放電ランプ点灯装置100を表す説明図である(非特許文献1参照)。図1に示すように、直流点灯放電ランプ点灯装置100は、ランプと、ランプを始動(絶縁破壊)させ、アーク放電への移行を行うイグナイタと、アーク放電の維持を行うためにランプ電流を制御する点灯装置とで構成される。
太陽電池のI-V特性測定は、ランプがアーク放電の維持を行っているときに実行されるため、このアーク放電を維持する時間は長いほうが好ましい。
光技術情報誌「ライトエッジ」No.15特集 放電ランプ(1998年11月発行)
また、近年では、測定に数百ミリ秒かかるようなI-V特性測定性能が要求される高効率の太陽電池が発明・開発されている。この高効率の太陽電池のI-V特性測定に対応する太陽光生成装置として、従来のフラッシュ放電ランプを用いたものでは、コンデンサーの容量が小さく、アーク放電を維持する時間が非常に短くなってしまうという問題点があった。そこで、電力を蓄積するコンデンサーの容量を大きくすることにより、アーク放電を維持する時間を長くすることも考えられるが、点灯装置の回路規模が大きくなってしまい、現実的ではない。
さらに、フラッシュ放電ランプにおいては、放射照度の時間的変化が大きいためI-V特性測定に必要な放射照度が一定とならず、高効率の太陽電池の正確な測定ができないという問題点があった。
つまり、疑似太陽光生成のための点灯装置に、大容量の電気二重層蓄電器を使用することにより、電源を小型化することが可能となる。また、蓄電容量の大きい電気二重層蓄電器の使用により、従来短かった点灯装置の点灯時間を必要十分な時間に延長することができる。
さらに、点灯時の照度を連続点灯で採用されている負帰還制御およびD級アンプ方式を取り入れることで、負帰還制御を円滑に行い、放射照度の安定化が図られる。

図3に示すように、疑似太陽光生成装置1は、商用電源11、充電電源12、電気二重層蓄電器および電力制御回路20、スイッチング方式昇圧電源回路30、D級アンプ回路40、アンプ出力制御回路45、フラッシュランプ50、電流検出器60、制御回路70、発光光量検出センサー80から構成されている。
商用電源11は充電電源12に接続しており、また、充電電源12は電気二重層蓄電器および電力制御回路20に接続している。電気二重層蓄電器および電力制御回路20にはフラッシュランプ50が接続され、電流が流れることにより点灯する。ここで、フラッシュランプ50を点灯させるための電気回路上にはスイッチング方式昇圧電源回路30、D級アンプ回路40、電流検出器60が設けられている。なお、D級アンプ回路40はフラッシュランプ50の上流部(下流部でもよい)、電流検出器60はフラッシュランプ50の下流部(上流部でもよい)にそれぞれ設けられ、スイッチング方式昇圧電源回路30は電気二重層蓄電器および電力制御回路20の上流部及び下流部に接続するよう設けられている。
まず、制御回路70の充電制御により、商用電源11に接続される充電電源12から、電気二重層蓄電器および電力制御回路20に電力が供給され、充電が行われる。そして、電気二重層蓄電器および電力制御回路20の充電が完了した後、制御回路70によってスイッチング方式昇圧電源回路30を制御し、所定の電圧を平滑コンデンサー38に蓄電させ、フラッシュランプ50の点灯準備が完了する。
ここで、制御回路70による上記定電流制御における定電流の値は、光量制御において、フラッシュランプ50の光量が所定の光量となるように定められる。
D級アンプ回路40は上述した問題点を解消するため、スイッチング方式昇圧電源回路30から出力される電圧を入力し、アンプ出力制御回路45からの制御に従ってフラッシュランプ50への電圧を制御する。
これによりD級アンプ回路40に吐き出しと吸い込み定電流特性を持たせることで、負荷用平滑コンデンサー38の電荷が負荷への突入電流を防止でき、また、電流の吸い込み性があるため、オーバーシュートを抑えることができる。負荷用平滑コンデンサー38を、目的とする最大電圧にし、D級アンプ回路40で吸い込みのある1、2、3象限型定電圧定電流特性で安定した制御が行われる。
負荷変動とその応答は、非線形であり、アナログ制御方式では目的とする特性を達成できないので、DSP等を使用し、デジタルで過渡応答を予測的に制御することで、応答特性を最適に制御できる。
しかし、フラッシュランプ50の光の放射照度は、照射全域で比例していない。これは発光光量検出センサー80がフラッシュランプ50の照射光の一部しか検出していないためである。そこで、上記本発明の実施の形態において、フラッシュランプ50の照射全域の光量に比例した信号で光量全体を制御し、放射照度の安定度をさらに高めることがより望ましい。
図5に示すように、低反射率ミラー92はフラッシュランプ50と太陽電池90の間に設けられ、また、低反射率ミラー92と発光光量検出センサー80との間には集光レンズ94が設けられている。
なお、特に積分レンズ等を使用して、全体を均一化しているソーラーシミュレータの場合は、局部の小さい変動があり、光量検出を照射全域の光から行う効果は大きい。
また、発光光量検出センサー80において検出する光のスペクトル分布を太陽電池90のスペクトル分布と同じにするためのフィルターを発光光量検出センサー80の検出部に設けることも考えられる。この場合に、発光光量検出センサー80は、該フィルターを介して太陽電池90のスペクトル分布と同じスペクトルの範囲だけにおいて光量を検出するため、スペクトル変動の影響を最小限に抑えることが可能となる。
図6は光ファイバーを用いた光量検出方法の説明図である。フラッシュランプ50と太陽電池90の間には反射集光ミラー110が設けられ、また、フラッシュランプ50の反射集光ミラー110と反対側には、光ファイバー120が接続される集光器125が設けられている。なお、反射集光ミラー110の中央部はフラッシュランプ50の光を透過させる構造となっており、また、光ファイバーの先端出力方向は、太陽電池90の方向である。
従って、太陽電池90に対するフラッシュランプ50からの光の照射照度の場所むらを改善することが可能となる。
