Abstract
Description
Vpk=Vic+R・Imax
の関係が成り立つと考えられる。そのため、取得したVpk、Vic、及びImaxの値から、以下の計算式により抵抗Rの値が算出される。
R=(Vpk−Vic)/Imax
Vtg=Vic+Iic・R
ここで、Iicは0からImaxまでの範囲で変動すると想定されるので、目標電圧Vtgは、Vicを下限、Vpkを上限とする範囲で設定されることになる。また、目標電圧Vtgは、Vpk、Vic、及びImaxの情報に基づいて決定された抵抗Rの値を比例定数として、Iicの1次関数として算出される。すなわち、抵抗Rの値が、電流Iicの時間変化に対する目標電圧Vtgの変化量を示している。
Vtg=Vic+Iic・R+α
Vpk−Vdrop=Vic
という関係が成り立つ。この場合に制御部11が実行する処理フローの一例について、図7のフロー図を用いて説明する。
Vtg=Vpk−Vdrop+R・Iic+α
ここで、αは、前述した例と同様の補正値である。
R=Vdrop/Imax
また、この図7のフローの例では、抵抗Rも装置要求電圧Vpk等と同様に集積回路装置30から取得することとしたが、集積回路装置30の個体差による抵抗Rのばらつきが小さければ、抵抗Rの値は固定値として予め電源回路10に書き込まれていてもよい。
