| description | To provide a power supply device capable of further reducing an output voltage without complicating control.SOLUTION: A power supply device comprises: a bridge circuit that includes an arm of at least one phase; a transformation circuit that includes at least one phase; and a control circuit that outputs first to fourth switching signals to first to fourth switching elements. In a first case where the switching signals have a predetermined frequency or less, the control circuit performs first control of changing a frequency while keeping a duty of the switching signals at a standard value. In a second case where the switching signals reach a predetermined frequency, the control circuit performs second control of setting the duty of the first switching signal to be lower than the standard value while keeping the frequency of the switching signals at the predetermined frequency.SELECTED DRAWING: Figure 1
【課題】制御を煩雑にすることなく、出力電圧を更に下げることができる電源装置を提供する。【解決手段】電源装置は、少なくとも１つの相のアームを含むブリッジ回路と、少なくとも１つの相を含む変圧回路と、第１スイッチング信号から第４スイッチング信号までを第１スイッチング素子から第４スイッチング素子までに出力する制御回路と、を備える。制御回路は、スイッチング信号が予め定められた周波数以下の第１の場合に、スイッチング信号のデューティを標準値に維持し、周波数を変更する第１制御を行い、スイッチング信号が予め定められた周波数に達した第２の場合に、スイッチング信号の周波数を予め定められた周波数に維持し、第１スイッチング信号のデューティを標準値よりも小さくする第２制御を行う。【選択図】図１ |
