Abstract
Description
実施の形態1は図1〜図3を参照しながら説明する。図1に示す電力変換装置10は、フルブリッジ型スイッチング電源装置(DC−DCコンバータ)の一例である。当該電力変換装置10は、入力電圧Vin(例えば288[V]等)を所要の出力電圧Vout(例えば14[V]等)に変換して出力する機能を担う。電力変換装置10の入力端子Tinには電力源Ebが接続され、出力端子Toutには負荷Zが接続される。電力源Ebは、例えばバッテリ(二次電池等)や燃料電池などが該当する。負荷Zは、例えば電力源Ebとは電源容量が異なるバッテリ、回転電機(電動発電機、発電機,電動機等)、ヘッドランプなどが該当する。出力電圧Voutは任意の値で設定してよい。電力変換装置10内に設定してもよく、外部処理装置(例えばECUやコンピュータ等)から伝達される信号やデータ等に基づいて設定してもよい。
図2に示す第1制御例は、入力電圧Vinが低電位閾値Lthよりも下回る状態と、高電位閾値Hthよりも上回る状態までの間で変化する場合の制御例を示す。入力電圧Vinが低電位閾値Lthよりも下回る時刻t11までは、状態信号Siと第1保護停止信号S1はローレベルLで維持され、第2保護停止信号S2はハイレベルHで維持される。これらの信号に従って、制御信号PLSが出力されないため、制御信号PLSも出力されない。この状態は、入力電圧Vinの安定性を判断するため、が所定範囲Vsp内に入る時刻t11から所定期間Tdを経過する時点(すなわち時刻t12)まで継続される。
図3に示す第2制御例は、第1制御例と同様の範囲で入力電圧Vinが変化するものの、高電位閾値Hth付近で微少変化が一時的に継続する場合の制御例を示す。入力電圧Vinが高電位閾値Hthを上回る時刻t23までは、第1制御例と同様に制御される。すなわち、時刻t22まではスイッチング素子Q1〜Q4の駆動を停止し、時刻t22から時刻t23まではスイッチング素子Q1〜Q4のオン/オフが駆動するように制御される。
実施の形態2は図4を参照しながら説明する。なお、電力変換装置10の構成等は実施の形態1と同様であり、図示および説明を簡単にするために実施の形態2では実施の形態1と異なる点について説明する。よって実施の形態1で用いた要素と同一の要素には同一の符号を付して説明を省略する。
以上では本発明を実施するための形態について実施の形態1,2に従って説明したが、本発明は当該形態に何ら限定されるものではない。言い換えれば、本発明の要旨を逸脱しない範囲内において、種々なる形態で実施することもできる。例えば、次に示す各形態を実現してもよい。
