 note = {コンバータの設計には制御やシステムの安定性を決める周波数特性を考慮する必要がある.入力や出力インピーダンスの周波数特性はNyquistやMiddlebrookの判別法による安定解析のために必要不可欠である.しかしながらコンバータの振る舞いはスイッチ動作により基本的に非線形であって,限られた場合以外は解析的な計算は実際的には不可能である.そのためシミュレータを用いた摂動法に基づく新しい数値処理法を提案する.提案法を,入力やループゲイン特性を求めるため,降圧形,昇圧形,昇降圧形,Cukコンバータに適用する.その結果は実験特性と比較したところよく一致した.提案法は検証された., It is necessary for a converter design to consider its frequency characteristics which determine its control and system stabilities. The frequency characteristics of input impedances and/or output impedances are indispensable to analyze stabilities of the system according to the Nyquist or the Middlebrook criterion. However, It is practically impossible to calculate frequency characteristics analytically except for limited cases because converter behaviors are basically nonlinear due to switching operations. A new numerical processing method which is based on the perturbation method by a simulator is proposed. The proposed method is applied to the buck, boost, buck-boost, Cuk, converters for their input and loop-gain frequency analyses. The results are compared and coincided well with measured characteristics. The proposed method is validated., application/pdf},
