Abstract
Description
−誘導性磁化モードにおいてエネルギを蓄積するとともに、誘導性減磁モードにおいてエネルギを転送する誘導性回路と、
−少なくとも2つの非反転出力電圧を提供する少なくとも2つの非反転分岐と、
−反転出力電圧を提供する反転分岐と、
を備え、
前記反転分岐及び前記非反転分岐が、前記誘導性回路の出力に並列接続され、前記誘導性回路が、前記反転分岐へ及び前記少なくとも2つの非反転分岐のうちの1つへエネルギを転送し、前記反転電圧及び前記少なくとも2つの非反転分岐のうちの1つの対応する非反転出力電圧が、逆の極性及び略等しい大きさを有する。
がインダクタのインダクタンスを表し、tが時間を表す場合に、I1がI1=(Vi/L)*tに等しいことを当業者によって容易に理解され得る。したがって、磁化電流ILは、例えば図2の屈曲線20に示されるように、ILがImaxに等しくなるまで時間とともに連続的に増加する。誘導性磁化モードにおいて、電流ILは、E=1/2*L*I2maxに等しいエネルギEの量を誘導性回路Lに転送することが容易に理解され得る。
として表現され得る。誘導性減磁モードにおいて、インダクタの両端の
ボルトの電圧は、例えば図3に示される屈曲線32のように、負性極性を有する。しかし、
が、出力電圧Vbに対して正の寄与を有することは明らかである。VD2は、用いられる技術に応じて、通常0.3及び0.7ボルト間に存在するダイオードD2の両端の電圧を表す。ダイオードD1、D2及びD3は、電圧変換器の出力から内部ノード10への電流漏れを防ぐために提供される。ダイオードD1、D2及びD3は、スイッチS5及びS6が、厳密に片方向である場合、すなわち内部ノード10から出力へのみ伝導する場合、省略され得る。このことは、例えば、スイッチS5及びS6が非直列接続であるP型MOSトランジスタの対を用いて構築される場合である。この場合、分岐12が、スイッチ装置も備えなければならないことが明らかである。スイッチS5及びS6が開いている場合、電流I2は、分岐12を通じて流れ始める。スイッチS5が閉じ、S6が開いた状態にされる場合、Vb-VD2の電圧が、内部ノード10に与えられる。これがVaより低い電圧であるので、ダイオードD1はオフにされ、I2は、第2分岐13を通じて流れ始める。同様にS6を閉じることにより、電圧Vc-VD3が内部ノード10に与えられ、ダイオードD1及びD2をオフにし得る。したがって、スイッチSL、S5及びS6を制御された方法で動作させることによって、インダクタLを磁化及び減磁すること、及び分岐12、13及び14のうちのそれぞれ1つにインダクタLからエネルギを転送することが可能である。コンデンサC1は、入力ラインを、電圧変換器のスイッチングノイズ及び高周波数スイッチング入力電流に対して保護する直流入力バッファとして動作する。コンデンサC2、C3及びC4は、直流出力バッファとして作動する。これらの機能は、第1に、高周波数出力電流を平滑にし、第2に、電圧変換器の分岐に何の充電も供給されない期間に連続的な出力電圧を保障することである。この結果として、C2、C3及びC4の両端の電圧は、わずかな交流リップルを示し得る。しかし、このことは、コンデンサC2、C3及びC4が誘導性回路によって十分早い程度に再充電されるので、あまり重要でない。
がインダクタLのインダクタンスである場合に、ILが
に等しいことは容易に理解され得る。SLが開かれると、電流ILはImaxに等しく、図2に示されるように下降エッジ22を示し得る。この下降エッジは、Viが入力電圧を示す場合、
として表現され得ることは容易に理解され得る。Voutは、図1の出力電圧Va、Vb、Vcの何れかを表し、VDは、ダイオードが伝導状態にある場合の、ダイオードD1、D2及びD3の両端の電圧降下を表す。
