Abstract
【解決手段】DC電力をDCリンク84に与えるように構成された発電システムが記載されている。発電システムは、DC電力を出力するように構成された第1の発電ユニット22を備えている。発電システムはまた、入力部90および出力部92を備える第1のDC−DCコンバータ70を備えている。第1のDC−DCコンバータ70の出力部は、第1の発電ユニット22と直列に結合されている。第1のDC−DCコンバータ70は、第1の発電ユニット22によるDC電力出力の第1の部分を処理するように、また第1の発電ユニット22のDC電力出力の未処理の第2の部分を出力部に与えるように、構成されている。
【選択図】図2
Description
この非反転バック・ブースト・コンバータ関係によって、DC−DCコンバータ402を広範囲のVmppt152変化に渡って用いることができる(たとえば、Vs150は、Vmppt+Vs=VDClinkとなるように、Vmpptより高い場合も低い場合もある)。Vmppt152がVDClink154よりも低いときには、入力電圧Vmppt152のうち一部分のみをDC−DCコンバータ402を通して処理する。処理する一部分は、Vmppt152とVDClink154との間の電圧差に依存する。より具体的には、電力のうちDC−DCコンバータ402によって処理される一部分は、Vmppt≦VDClinkのときに、次式を用いて計算しても良い。
Vmppt152が実質的にVDClinkに等しいときには、入力電力はすべてDC−DCコンバータ402を通過し、処理および/または変換されることはない(すなわち、Vmppt152はすべて出力部92に送られ、トランジスタ403は「OFF」状態にされる)。Vmppt152が所定の電圧レベルを超えたときには、トランジスタ403は、「ON」状態に留まることによってVmppt152を制限するように構成されている。「ON」状態に維持されているときには、トランジスタ403によって、PVアレイ電圧152(Vmppt)が所定のレベルを超えること(たとえば、起動中に、および/または極めて冷たくて明るい条件で起こる場合がある)はない。
