Description
これが起きるメカニズムは以下のとおりである。
・二次側電源供給を、充電出力と別系統にする。つまり、充電出力が低下しても、二次側電源供給が途絶えないような回路構成にする。例えば、充電出力については、上記の従来技術のように定電圧充電となるように、フィードバックをかけるが、二次側電源供給については、充電出力に利用するトランスとは、別のトランスから常に出力を得るようにする。これにより、充電出力が停止、間欠発振しても、二次側電源供給を行うことができるので、二次側のマイコン、IC等は引き続き利用することができる。これにより、マイコンのシャットダウン等は発生しない。
・高精度で電圧検出できる素子を用い、充電出力電圧と電池電圧を比較し、充電出力電圧より電池電圧のほうが高い場合には充電開始しないようにする。
しかし、いずれの対策にしても、回路部品が追加になったり、高価な部品を使用する必要があった。
