Description
E=1/2×C×(V12−V22) ・・・(1)
これより、蓄電用コンデンサ30が供給できる電力を大きくするためには、蓄電用コンデンサ30の容量値Cを大きくするか、あるいはコンバータ10Yの出力電圧の上限値と下限値との電位差(V1−V2)を大きくする必要がある。
E=1/2×C×(V12−V22) ・・・(1)
E=1/2×C×(V12−V22) ・・・(1)
ここで、蓄電用コンデンサ30が供給すべき最大エネルギーEは、モータ3の駆動条件(例えば、モータ3の加速動作に必要なエネルギー、及び/又は、モータ3の減速動作で回生されるエネルギー)に基づいて算出されればよい。これにより、モータ3の加速時に、DC/DCコンバータ40の出力電圧が上限値V1から下限値V2に低下するまでDC/DCコンバータ40の出力電流を制限しても、不足分を蓄電用コンデンサ30から供給することができる。
まず、モータ3の停止時又は低速動作時(図3の時刻t0〜時刻t1)、DC/DCコンバータ40の制御部49は、第1電圧センサ61で検出された入力電圧値と第2電圧センサ62で検出された出力電圧値とに基づいて、力行用スイッチ素子41、昇圧用スイッチ素子44及び回生用スイッチ素子46を制御することにより、DC/DCコンバータ40の出力電圧を目標値V1に昇圧制御する。例えば、DC/DCコンバータ40の出力電圧の目標値V1は、インバータ20の耐圧及びモータ3の耐圧の何れか小さい方の耐圧V3の95%程度である。
次に、モータ3の加速時(図3の時刻t1〜時刻t2)、インバータ20の入力電流の増加に伴い、DC/DCコンバータ40の出力電流が増加する。そして、第1電流センサ51で検出されたインバータ20の入力電流値に基づいて、インバータ20の入力電流値が所定の最大出力電流値I1に達したとき(図3の時刻t2)、力行用スイッチ素子41、昇圧用スイッチ素子44及び回生用スイッチ素子46を制御することにより、DC/DCコンバータ40の出力電流を所定の最大出力電流値I1に制限する。このとき、制御部49は、DC/DCコンバータ40の出力電圧を次第に低下させる(図3の時刻t2〜時刻t3)。
次に、モータ3の定速動作時(図3の時刻t3〜t4)、制御部49は、DC/DCコンバータ40の出力電圧を下限値V2に降圧する制御を継続する。
次に、モータ3の減速時(図3の時刻t4〜時刻t5)、モータ3から大きな回生電流が回生されることに伴い、インバータ20から大きな回生電流が回生される。このとき、第1電流センサ51で検出されたインバータ20の回生電流値に基づいて、力行用スイッチ素子41、昇圧用スイッチ素子44及び回生用スイッチ素子46を制御することにより、DC/DCコンバータ40の回生電流を所定の最大回生電流値I2に制限する。
