L>(VCC2×Ton×Toff)/(2×IG×(Ton+Toff)) ・・・(1)
実施形態に係るDCDCコンバータ1について説明する。DCDCコンバータ1は、図1に示すように、例えば、絶縁型のスイッチング電源装置である。DCDCコンバータ1は、例えば、車両の直流電源(バッテリ)から供給される直流電力の電圧を変圧するものである。DCDCコンバータ1は、1次回路10と、2次回路(図示せず)と、1次回路10を制御するスイッチング制御装置20とを備えている。1次回路10は、スイッチング回路11と、スイッチング回路11に接続される1次巻線12とを備えている。スイッチング回路11は、変圧対象の直流電源VPPに接続され、直流電源VPPから供給される直流電力を交流電力に変換する回路である。ここで、直流電源VPPは、相対的に高い電圧であり、例えば100V〜200V程度の電圧である。スイッチング回路11は、例えば、4つのスイッチング素子から構成されるフルブリッジ方式の回路である。図1では、スイッチング回路11において2つのスイッチング素子Q1、Q2を図示し、残り2つのスイッチング素子の図示を省略している。各スイッチング素子Q1、Q2は、例えば、Nチャネル型のMOSFET(Metal-Oxide-Semiconductor Field-Effect Transistor)であり、以下、単にFETQ1、Q2ともいう。FETQ1は、入力端子としてのドレイン端子d1が電源VPPに接続されている。2次回路(図示せず)は、1次巻線12に対向して設置される2次巻線と、2次巻線に接続され2次巻線から出力される交流電力を直流電力に整流する整流回路と、整流回路に接続され整流回路から出力される直流電流を平滑化する平滑回路とを備えている。DCDCコンバータ1は、直流電源VPPから供給される直流電力をスイッチング回路11により交流電力に変換し、変換した交流電力を1次巻線12及び2次巻線により変圧し、変圧された交流電力を整流回路により整流し、整流回路により整流された直流電力を平滑回路により平滑化して負荷部に供給する。

次に、実施形態の変形例について説明する。駆動回路21Aは、1次巻線PT1及び2次巻線PT2によりパルストランスを構成する例について説明したが、これに限定されない。例えば、駆動回路21Aは、図3に示すように、パルストランスの代わりにフォトカプラ21aを用いてもよい。この場合、駆動回路21Cは、フォトカプラ21aが発光素子21bと、受光素子21cとを備えている。発光素子21bは、例えば発光ダイオードであり、アノード端子が抵抗R1を介してトランジスタQ3とトランジスタQ4との間に接続され、カソード端子がグランドに接続されている。受光素子21cは、例えばフォトトランジスタであり、一端がFETQ5のゲート端子及びFETQ6のゲート端子に接続され、他端がコンデンサC4に接続されている。駆動回路21Cは、発光素子21bに電流が流れることにより発光素子21bから光信号を出力し、発光素子21bから出力された光信号を受光素子21cにより受光する。そして、駆動回路21Cは、受光した光信号を電気信号(パルス信号)に変換してFETQ5のゲート端子及びFETQ6のゲート端子に出力し、当該FETQ5、Q6をオン・オフ制御する。このように、駆動回路21Cは、フォトカプラ21aを有する構成としてもよい。
