Abstract
Description
マイクロコンピュータ(以下、「マイコン」)を備えている。マイコンは、調光操作部で設定された調光レベルに応じて、交流電圧の半サイクル毎の期間途中で、照明負荷への給電を遮断する逆位相制御を行う。
(1.1)構成
本実施形態の調光装置1は、図1及び図2に示すように、一対の入力端子11,12と、スイッチ素子Q1,Q2と、入力部4と、信号源910と、放電部920と、を備えている。
本実施形態の調光装置1の調光動作について、図3を参照して説明する。図3では、交流電圧Vac、第1制御信号Sb1、及び第2制御信号Sb2を示している。
(1.3.1)駆動部の構成
第1駆動部91及び第2駆動部92の構成について、さらに詳しく説明する。以下では、第1駆動部91と第2駆動部92とに共通する構成を「駆動部90」とし、駆動部90が第1駆動部91に適用されている場合を例として説明する。
次に、駆動部90の動作について図4を参照して説明する。ここでは、駆動信号Sd1が「L」レベル、「H」レベル、「L」レベルの順に変化する場合の駆動部90の動作を例示する。さらに、ここでは第1の入力端子11が高電位側、第2の入力端子12が低電位側となる電圧が、入力端子11,12間に電圧がかかっている状態(交流電圧Vacの正極性の半周期)を想定する。なお、図4では、横軸を時間軸として、駆動信号Sd1、ゲート電圧Vg1、及びドレイン電流(スイッチ素子Q1のドレイン−ソース間を流れる電流)Id1を示している。駆動信号Sd1については0〔V〕が「L」レベルに相当する。
以下、本実施形態における駆動部90の構成から放電部920を省略した構成の駆動部を持つ調光装置を比較例とし、本実施形態における駆動部90と比較例における駆動部とを対比した場合の、両者の相違点について説明する。ここで示す比較例は、放電部がない点で本実施形態とは異なるものの、その他の回路構成については本実施形態と同じであるため、以下、本実施形態と同様の構成要素については共通の符号を付して説明する。
本実施形態の調光装置1は、放電部920を備えることにより、信号源910の発生する駆動信号Sd1が「L」レベルに変化した直後には、ゲート電圧Vg1を急峻に低下させることができる。これにより、放電部920がない場合に比べて、各スイッチ素子Q1,Q2のオフ制御時の遅延時間が小さくなり、調光レベルに対する負荷7の光出力の応答性が向上する。また、スイッチング損失も小さくなる。したがって、本実施形態の調光装置1によれば、より多くの種類の負荷に対応可能になる、という利点がある。
(1.5.1)変形例1
実施形態1の変形例1に係る調光装置1Aは、図6に示すように、双方向スイッチ2に相当する部分が、実施形態1の調光装置1と相違する。以下、実施形態1と同様の構成については共通の符号を付して適宜説明を省略する。
以下、上述した変形例1以外の実施形態1の変形例を列挙する。
本実施形態の調光装置1Bは、図7に示すように、制御端子20と信号源910の基準電位点との間の導通・非導通を切り替えるように構成されている補助スイッチQ11を、さらに備える点で、実施形態1の調光装置1と相違する。図7では、実施形態1の図2と同様に、第1駆動部と第2駆動部とに共通する構成を「駆動部」とし、駆動部90Bが第1駆動部91Bに適用されている場合を例示している。以下、実施形態1と同様の構成については共通の符号を付して適宜説明を省略する。
上述の実施形態1(変形例を含む)及び実施形態2では、交流電圧Vacの半周期の始点(ゼロクロス点)t0の前後(第一の期間T1、第四の期間T4)に亘って、交流電源8から電源部5への電力供給を確保しているが、これに限られない。
