Abstract:
(EN) According to the present invention, in a case where a DC/DC converter (1) in a light load state is operated in a current discontinuous mode, when a control resolution, which is higher than a control resolution achieved by a pulse width modulation control, is required, a pulse width setting unit (7) executes a pulse width setting process and a pulse period setting unit (8) executes a pulse period setting process.
(FR) Selon la présente invention, dans un cas où un convertisseur CC/CC (1) dans un état de charge de lumière fonctionne dan un mode discontinu de courant, lorsqu'une résolution de commande, qui est supérieure à une résolution de commande obtenue par une commande de modulation de largeur d'impulsion, est nécessaire, une unité de réglage de largeur d'impulsion (7) exécute un processus de réglage de largeur d'impulsion et une unité de réglage de période d'impulsion (8) exécute un processus de réglage de période d'impulsion.
(JA) 軽負荷状態のDC/DCコンバータ(1)を電流不連続モードにて動作させる場合において、PWM制御による制御分解能よりも高い制御分解能が要求されるとき、パルス幅設定部(7)がパルス幅設定処理を実行するのに加えてパルス周期設定部(8)がパルス周期設定処理を実行する。
