Abstract
【解決手段】駆動命令手段の操作による駆動命令信号が第1の入力しきい値以下になったことを入力回路(Q1,R1,R2)で検出し、それにより起動される定電流源(1)で、さらに所定の周波数およびデューティ比を有するPWM信号を生成するPWM信号生成手段(3)と、第1の入力しきい値より低く設定された第2の入力しきい値と駆動命令信号を比較するコンパレータ(2)とを起動し、PWM信号と比較結果出力との論理演算を論理演算手段(4)で行い、その出力に応じて駆動制御手段(Q3,Q4,R6,R7,D1)でPWM駆動制御信号を生成し、生成されたPWM駆動制御信号で負荷駆動素子(5)を駆動して負荷(6)をPWM制御する。
