Abstract
Description
ここで、XC1は、第1のコンデンサのリアクタンスである。従って、第1のコンデンサのリアクタンスは、好ましくは、所要負荷抵抗RLと共振回路の所要入力抵抗Rinとの積の平方根に等しい。
である。
ここで、XL1、XL2、XC1は共振回路部品L1、L2、C1のそれぞれのリアクタンスであり、Vは励起電圧、RLは負荷の実効抵抗、jは無効成分である。
この場合には、負荷中の電流は、負荷に依存せず、入力電源電圧に比例する。
となり、これを変形すると、次のようになる。
Claims (1)
- 交流電源接続用の入力部と、
負荷駆動に好適な出力を提供する前記入力部に結合した共振回路と、
を備える、電源アダプタであって、
前記共振回路のキャパシタンスとインダクタンスとは、前記電源アダプタの入力と出力との間に、実効電圧の所定変化と対応する実効電流の所定変化とを提供するように、選択される、
電源アダプタ。
