Description
図1及び図2は、この発明の実施の形態1による電力変換装置の回路構成図である。
この実施の形態1の電力変換装置は、例えば、電動車両の充電器を中心とした電源システムに適用されるものである。交流電源1は商用交流電源や自家発電機などであり、第1の直流電圧源11は車両走行用の高圧バッテリであり、第2の直流電圧源34は車両電装品の電源である鉛バッテリ等のバッテリであり、インバータ17は車内で使用可能な交流100V電源を供給する、電源システムに適用可能である。
また、制御部100は第1〜第4のスイッチング回路4、8、13、30や、インバータ17の動作を制御する役割を果たす。
交流電源1が接続されていてこの交流電源1を電源システムの電力供給源とする場合、交流電源1の電圧VacinをAC/DCコンバータ2で直流電圧VL1に変換し、この直流電圧VL1をトランス6で絶縁された2次側直流電圧Vbat1に変換して第1の直流電圧源11を充電する。また、直流電圧VL1は、トランス6で絶縁された3次側の直流電圧VL2に変換され、インバータ17により直流−交流変換され、負荷機器接続端21に接続される交流負荷に対する交流電圧Vacoutを生成する。さらに、直流電圧VL1はトランス6で絶縁された4次側の直流電圧Vbat2に変換されて第2の直流電圧源34を充電する。
なお、第3のスイッチング回路13、インバータ17、第4のスイッチング回路30のスイッチング素子33は、図6(a)〜(c)の場合と同様に動作する(図8(a)〜(c)参照)。
ここで、図11は、コンデンサ3の電圧VL1を特に考慮することなく、第1の直流電圧源11を放電させる場合である。その場合、AC/DCコンバータ2と第1のスイッチング回路4は共に動作を停止するとともに、第2のスイッチング回路8は、任意の時比率指令値Duty*による一定の時比率でPWM動作することで第1の直流電圧源11を放電させる(図11(a)参照)。
なお、第3のスイッチング回路13、インバータ17、第4のスイッチング回路30のスイッチング素子33は、図6(a)〜図6(c)の場合と同様に動作する(図11(b)〜図11(d)参照)。
なお、第3のスイッチング回路13とインバータ17は、図6(b)、図6(c)の場合と同様に動作する(図14(b)、図14(c)参照)。
この状態のままでは、第1の直流電圧源11の電圧Vbat1よりもトランス6の第2の巻線6bの電圧Vtr2の方が低いことから、第1の直流電圧源11に対して充電は行われない。
図17及び図18は、この発明の実施の形態2による電力変換装置の回路構成図であり、図1及び図2に示した実施の形態1と対応もしくは相当する構成部分には同一の符号を付す。
なお、インバータ17、第4のスイッチング回路30のスイッチング素子33は、図21(d)、図21(e)の場合と同様に動作する(図22(d)、図22(e)参照)。
なお、インバータ17、第4のスイッチング回路30のスイッチング素子33は、図21(d)、図21(e)の場合と同様に動作する(図25(c)、図25(d)参照)。
ここで、AC/DCコンバータ2は、動作を停止するとともに、第4のスイッチング回路30のスイッチング素子33は、任意の時比率指令値Duty*による一定の時比率でPWM動作することで、第2の直流電圧源34を放電させる(図28(c)参照)。
なお、インバータ17は、図21(d)の場合と同様に動作する(図28(d)参照)。
図31は、この発明の実施の形態3による電力変換装置の回路構成図であり、図1及び図2に示した実施の形態1と対応もしくは相当する構成部分には同一の符号を付す。
したがって、実施の形態1における第4のスイッチング回路30や第2の直流電圧源34を含む回路の動作を除けば、基本的な動作は、実施の形態1と同様であるから、ここでは詳しい説明は省略する。
図32は、この発明の実施の形態4による電力変換装置の回路構成図であり、図1及び図2に示した実施の形態1と対応もしくは相当する構成部分には同一の符号を付す。
したがって、実施の形態1における第3のスイッチング回路13やインバータ17を含む回路の動作を除けば、基本的な動作は、実施の形態1と同様であるから、ここでは詳しい説明は省略する。
