Description
本開示は、一般的には、負荷に対して供給される電力を制御することに関する。 いくつかの実施例においては、負荷に対して、その負荷からのフィードバック(例えば、負荷電圧および負荷電流の監視)、および/または負荷電圧または負荷電流の調整を必要とすることなく、制御された所定の電力が供給される。
DC‐DC変換器は、DC入力電圧を受け入れて、DC出力電圧を供給する周知の電気デバイスである。DC‐DC変換器は、一般に、調整されていないDC入力に基づいて、調整されたDC出力電圧を負荷に対して供給するように構成されており、この入力電圧は、場合によっては、調整された出力電圧と異なる。例えば、バッテリが約12ボルトの無調整電圧を有するDC電源となる、多くの自動車用途においては、DC‐DC変換器を使用して、無調整12ボルトDCを入力として受け入れ、調整DC電圧を供給して、車両内の種々の電子回路(計器類、アクセサリ、エンジン制御、照明、ラジオ/ステレオ、その他)を駆動することもできる。調整DC出力電圧は、バッテリからの入力電圧よりも低くするか、または高くするか、あるいは同じにすることができる。
定常動作に対して、ここで認識すべきことは、スイッチングサイクルの開始および終了における、インダクタ電流ILは、図3における表示IOによって分かるように、本質的に同じである。したがって、VL=L・dIL/dtの関係から、1回のスイッチングサイクルにわたる電流の変化dILはゼロであり、次式によって与えられ:
この配設において、トランジスタスイッチ20がオフまたは開放の場合に、抵抗器Rsenseを通過する電流は存在せず、したがって、コンパレータ62の反転入力における電圧はゼロである。ここで、図1から思い起こされるのは、この実施例における誤差信号38は、サンプリング出力電圧VsampleとVrefの差を示す、ある所定の範囲にわたる正の電圧である。したがって、トランジスタスイッチ20が開放の場合には、コンパレータによって出力される信号64は、論理ハイ信号である(すなわち、フリップフロップのリセット入力
フリップフロップがこの状態にあると、パルスストリーム42の次のロー行き(low going)パルスは、フリップフロップのセット入力
VAC=IACRPFC
または
GPFCVAC=IAC
となり、ここで、GPFC=1/RPFCであり、力率補正装置520の有効コンダクタンスを表わす。
本開示の様々な態様は、全般的には少なくともある種の負荷に対して電力を供給して制御するための方法および装置を目的としており、従来型配設と比較して、一般に全体電力効率が改善され、また構成要素の機能的冗長性が大幅に低減される。異なる観点においては、本開示の様々な態様による方法および装置の実現には、一般的に、少数の構成要素、高い全体的電力効率、および小さいスペース要求を有する、大幅に簡略化した回路を伴う。
出願者らは、電源用途および負荷の種類によっては、DC−DC変換器に基づく市販の従来形スイッチング電源は、負荷に対する柔軟かつ/または効率的な電力の供給を促進するのに最適に構成することはできないことを認識し理解していた。例えば、多くの従来型スイッチング電源の電力変換効率は、(AC線間電圧から調整DC電圧出力へ)約80%程度であるが、異なる負荷の特定の構成および/または制御要件は、DC‐DC変換器と、それ自体が様々な制御回路を含むことのある負荷とを含むシステムの、全体電力変換効率を大幅に低減させる可能性がある。
前述のことを考慮して、本開示は、全般的には、少なくともある種の負荷に対して電力を供給し制御する、様々な改良型方法および装置を目的とする。以下にさらに詳細に考察するいくつかの態様においては、制御された所定の電力が、負荷に対して、その負荷からのいかなるフィードバック情報も必要とすることなく(例えば、負荷電圧および電流の監視および/または調整なしに)供給され、それによって回路複雑性、構成要素数、寸法および効率を大幅に低減する。
P=(伝達当りのエネルギー量)×(時間間隔当りの伝達回数) (2)
この視点から、認識できることは、負荷への電力は、1)伝達当りのエネルギー量を調節すること、および2)それぞれが同量のエネルギーを有する伝達数を時間に対して変化させることの一方または両方によって、調節できることである。
