Abstract
Description
前記第1トランジスタにカスコード接続され、前記第1トランジスタの前記第2電極が接続される第2制御電極を有するノーマリオンの第2トランジスタと、
前記第1トランジスタの前記第1電極及び前記第2電極の間の電圧に基づいて制御電圧を生成する制御電圧生成器と、
前記制御電圧に基づいて、前記第1トランジスタの耐圧以下の前記駆動電圧を生成する駆動電圧生成器と、を備える電力切替器が提供される。
図1は第1の実施形態による電力切替器1の回路図である。図1の電力切替器1は、ノーマリオフの第1トランジスタQ1と、ノーマリオフの第2トランジスタQ2と、制御電圧生成器2と、駆動電圧生成器3とを備えている。
第2の実施形態は、第1の実施形態による電力切替器1を電力整流器に適用したものである。
第3の実施形態は、全波整流電圧を出力する同期整流回路を実現するものである。
第4の実施形態は、上述した電力切替器1を電力変換器に適用したものである。
このように、各DC−DCコンバータ25は、対応するローカルコントローラ29により制御されるが、複数のDC−DCコンバータ25を全体的に制御するマスタコントローラは設けられていない。これは、各DC−DCコンバータ25が、第6トランジスタQ6及び第7トランジスタQ7を一定の時比率でオン/オフ制御すれば、複数のDC−DCコンバータ25を全体的に制御しなくても、各DC−DCコンバータ25の入力電圧と出力電流が平衡する動作が自動的に行われるためである。
