Description
車載用の蓄電部に電気的に接続された第1導電路に印加された電圧を降圧して第2導電路に印加する降圧動作を少なくとも行う第1電圧変換部と、
前記第1導電路に印加された電圧を降圧して前記第2導電路に印加する降圧動作を少なくとも行い、前記第1電圧変換部よりも電力容量が小さい第2電圧変換部と、
第1の時期に前記第1電圧変換部及び前記第2電圧変換部のうちの前記第2電圧変換部のみを駆動し、前記第1の時期から第2の時期となったときに少なくとも前記第2電圧変換部を駆動する駆動部と、
前記第2導電路に電気的に接続され、前記第2導電路を流れる電流によって充電されるキャパシタと、
を有する。
以下、本発明を具体化した実施例1について説明する。
図1で示す車載用電源システム100(以下、電源システム100ともいう)は、高圧系の電源路81と低圧系の電源路82の二系統に電力を供給し得るシステムとして構成されている。電源システム100は、高圧系の電源路81に相対的に高い電圧(例えば48V程度)を印加し、低圧系の電源路82に相対的に低い電圧(例えば12V程度)を印加する電源システムとなっており、電源路81,82に接続された電気機器に電力を供給し得るシステムとして構成されている。
図1の電源システム100は、例えば、低圧系の電源路82にバッテリが接続されておらず、高圧系の電源路81に接続された蓄電部91の出力を降圧して低圧系の電源路82に供給するシステムとなっている。更に、高圧系の電源路81に発電機92や図示しないスタータが設けられている。このような構成では、車両の駐車中などに電源装置1の動作が完全に停止してしまうと、第2導電路32側に電力が供給されなくなってしまい、第2導電路32に電気的に接続された負荷を駆動できなくなる。そこで、車両の駐車中などの所定の時期(第1の時期)には、暗電流用回路20を動作させ、大出力用回路10の動作を停止させることで、出力電流を抑えた形で電力供給を行う。
図1等で示す車載用電源装置1は、第1の時期(例えば、イグニッションスイッチがオフ状態になっているとき)に電力容量が小さい第2電圧変換部22のみを動作させ、消費電力を抑えた形で出力を継続することができる。この第2電圧変換部22は、第1の時期に想定される電流に合わせた回路規模で良いため、大型化しすぎる必要はなく、回路構成を適正化しやすい。一方、第1の時期から第2の時期になったときには、電力容量が相対的に大きい第1電圧変換部12を駆動することで、より大きな電流を流すことができるようになる。
本発明は上記記述及び図面によって説明した実施例に限定されるものではなく、例えば次のような実施例も本発明の技術的範囲に含まれる。また、上述した実施例や後述する実施例は矛盾しない範囲で組み合わせることが可能である。
この車載用電源装置301は、第1電圧変換部12の駆動が停止し且つ第2電圧変換部22が駆動している時、即ち、消費電力を抑えた形で動作している第1の時期に第2導電路32の電圧が「所定の電圧値範囲」よりも低下した場合、その低下後の時期を「第2の時期」として第1電圧変換部12の駆動を開始してより大きな電流を出力することができる。更に、第2導電路32の電圧が所定電圧値よりも低下してから実際に第1電圧変換部12から電流が出力されるまでの間は、キャパシタ50からの電流によって出力を補うことができ、第1電圧変換部が大きな電流を出力するまでの出力の遅延を効果的に抑えることができる。
