Description
先ず、本願において開示される発明の代表的な実施の形態について概要を説明する。なお、以下の説明では、一例として、発明の構成要素に対応する図面上の参照符号を、括弧を付して記載している。
以下、本発明の実施の形態の具体例について図を参照して説明する。なお、以下の説明において、各実施の形態において共通する構成要素には同一の参照符号を付し、繰り返しの説明を省略する。
図1は、本発明の実施の形態に係る負荷駆動回路を備えたモータ駆動制御システムの構成を示す図である。
後述するように、抵抗R1,R2を設けることにより、保護用トランジスタQa,Qbのゲート・ソース間電圧Vgsが緩やかに上昇し、キャパシタC5,C6に流れ込む突入電流が抑制される。
上述したように、モータ駆動回路12のインバータ回路14の一つの出力端から出力される信号(一つのスイッチングレグSWwのスイッチング動作)に応じて、昇圧部16のキャパシタC1の一方の端子の電圧が駆動用電源端P7またはグラウンド電位(抵抗Rsを経由)に切り替わる。
図4は、本実施の形態に係るモータ駆動制御装置1における主要な電圧と制御回路11の動作内容を示すタイミングチャートである。
以下の説明では、一例として、モータ駆動制御システム100の初期状態においてモータ駆動制御装置1内の電源ラインLpを含む全てのノードの電圧が0Vであるとする。また、一例として、電源電圧Vdcが12Vであるとする。
なお、上述した昇圧部16の昇圧動作は、モータ3に大きな電流が流れ始める前に完了するため、モータ3の駆動と昇圧動作とを同時に開始しても問題ない。
したがって、本実施の形態に係る負荷駆動回路102によれば、モータ駆動制御装置1の保護機能をより低コストで実現することが可能となる。
以上、本発明者らによってなされた発明を実施の形態に基づいて具体的に説明したが、本発明はそれに限定されるものではなく、その要旨を逸脱しない範囲において種々変更可能であることは言うまでもない。
