Abstract
【解決手段】各負荷3を実際に流れた電流値とそのデューティー比を電流検出部114とDUTY比検出部115で検出して、負荷3の実供給電力値を電力データ算出部116で検出する。この実供給電力値が、その負荷3の目標電力値と一致するように、PWM制御のデューティー比をDUTY比補正値算出部117で算出し、PWM_DUTY比制御部113によるPWM制御のデューティー比として設定する。これにより、負荷3や負荷3に接続したワイヤハーネスの抵抗特性が経年変化や環境変化によって変動しても、変動後の抵抗特性に応じてPWM制御のデューティー比を補正し、目標電力値の電力が負荷3に供給される状態を維持することができる。
