Abstract
圧電トランスによる降圧の効率が高い直流低電圧電源装置を提供する。スイッチング素子131、132およびチョークコイル117を有し、スイッチング素子131、132の動作により直流入力電圧を交流電圧に変換する駆動回路110と、変換された交流電圧が入力されることで駆動され、降圧された交流電圧を出力する圧電トランス120と、スイッチング素子131、132およびチョークコイル136、137を有し、出力された交流電圧を直流電圧に変換する同期整流回路130と、を備え、圧電トランス120は、負荷140の抵抗に基づき、同期整流回路130の同期整流作用に応じて要求される圧電トランス120の出力電圧、および電力保存則から導かれる圧電トランス120の出力電流により定まる所定範囲の出力インピーダンスを有している。
