Abstract
【解決手段】それぞれ1つの極性を有する第1巻線と第2巻線とを含む結合インダクタ36は、その第1巻線と第2巻線とが同じ極性を持ち、それらが直列接続されて1つの共通ノードを形成し、第1巻線と第2巻線とはほぼ1に等しい結合係数を有する。前記結合インダクタ36と、入力電圧を結合インダクタ36に1つのスイッチング周波数で制御可能に導通するために、オン状態とオフ状態とを有する導通スイッチ32と、オン状態とオフ状態とを有し、導通スイッチがオフ状態のときに電流のための経路を提供するために結合インダクタ36の共通ノードにつながっているフリーホイーリングスイッチ34と、出力電圧をフィルタリングするために、結合インダクタにつながっている出力コンデンサ38とを備えることにより、電圧調整器30を構成する。
【選択図】図2A
Description
波形20は、導通スイッチ12の動作状態を示す。波形22は、フリーホイーリングスイッチ14の両端の電圧V1を示す。電圧V1は、1つの立ち上がり時間と1つの立ち下がり時間とが一般に約10nsecになりうる。一般に、この立ち上がり時間と立ち下がり時間とは、導通スイッチ12とフリーホイーリングスイッチ14とに使用される複数のスイッチの種類によって制限される。立ち上がり時間と立ち下がり時間とが長くなるにつれて、複数のスイッチング損失が増加しうる。波形24は、出力インダクタ16を流れる電流I1を示す。パルス幅が狭まるにつれて、複数の全電力損失に占める複数のスイッチング損失の1つの割合がより大きくなる。
この出力電圧をフィルタリングするために、少なくとも1つの結合インダクタにつながっている1つの出力コンデンサ。
導通スイッチ32およびフリーホイーリングスイッチ34は、個別に制御可能な1つまたは複数の並列スイッチ33a〜33cをそれぞれ備えてもよい。複数の並列スイッチ33a〜33cの全部または一部をオンにできるように、並列スイッチ33a〜3cのそれぞれを個別にイネーブル信号ENB1〜ENB3によって制御できるようにしてもよい。
次に、オン状態になった複数の並列スイッチ33a〜33cを同じ駆動信号Ф1によって制御してもよい。
結合インダクタ50の複数の巻線は、これら複数の巻線を流れる複数の電流が同じ方向に流れるように構成されている。
