図1は、直流低電圧電源装置100の構成を示す図である。図1に示すように、直流低電圧電源装置100は、駆動回路110、圧電トランス120、同期整流回路130、負荷140、検出用抵抗150、155、誤差アンプ160および電圧制御発振回路170を備えている。直流低電圧電源装置100は、たとえば入力段の整流回路と組み合わせてACアダプタとして用いられる。
図2は、直流低電圧電源装置100の出力電圧および出力電流と圧電トランス120の出力インピーダンスとの関係を示す模式図である。圧電トランス120は、圧電トランス120の2次側の持つ出力インピーダンスZOPTと負荷140の抵抗RLとがマッチングしたとき、高い効率で動作する。圧電トランス120の出力電圧の実効値をVOPT、直流低電圧電源装置100の出力電圧をVOUTとすると、マッチングの条件下ではVOPT=(π/√2)VOUTの関係が成り立つ。
ハーフブリッジ型の駆動回路110では入力される差動信号によりスイッチング動作が行われ、それにより直流電圧が矩形波上の交流電圧に変換される。さらに、駆動回路110のチョークコイル117と圧電トランス120の1次側の容量によるフィルタ効果により矩形波電圧はほぼ正弦波波形の交流電圧に変換され、圧電トランス120に入力される。このとき、ハーフブリッジ型の駆動回路110に入力される直流電圧をVINとしたとき、圧電トランスに入力される交流電圧VIPTの実効値は(3/√2π)VINとなる。
同期整流回路130に用いるチョークコイル136、137のリアクタンスが圧電トランス120の出力インピーダンスと等しいとき、同期整流回路130および圧電トランス120は高効率で動作する。ここで、直流低電圧電源装置100の出力電圧がVOUT、出力電流がIOUTであるとき、圧電トランス120の出力インピーダンスは(π2/2)(VOUT/IOUT)である。チョークコイル136、137のリアクタンスは(π2/2)(VOUT/IOUT)周辺であることが好ましい。したがって、この関係より、好適な同期整流回路のチョークコイルのインダクタンス容量はL=(π/4f)(VOUT/IOUT)と求まる。実際に、チョークコイルのインダクタンス値をこの近傍で変えて効率を測定したところ、下式の範囲で、高い電源効率を示した。なお、fは駆動周波数である。
次に、上記のように構成される直流低電圧電源装置100の動作を以下に説明する。まず、駆動回路110に電圧制御発振回路170から発振信号が伝えられる。そして、駆動回路110は、発振信号によりスイッチング素子111、112のオン、オフにより圧電トランス120に正弦波電圧を出力する。一般的には、圧電トランス120の駆動周波数をλ/2モードとする。
ンスを用いることが好適である。
