Description
Vehicle:電気自動車)等に用いられる車載充電器として、外部の電源から供給される電力に電力変換を施し、その結果得られる直流電圧によりEV内の蓄電池の充電を行う構成のものがある。また、この種の車載充電器の中には、電力変換のための手段としてインバータを含むものがある。
まず、上述した第1の従来技術では、本実施形態における入力電源端子301と補機電源との間にリレーを設ける必要があった。このため、充電器の回路規模が増大する問題がある。また、リレーの分だけ部品数が増加するため、製造コストが増加し、かつ、回路故障の発生率が高くなるという問題があった。
以上、この発明の一実施形態について説明したが、この発明には他にも実施形態が考えられる。例えば次の通りである。
