Description
ILoop*R1=IS*R3 式1
IS=ILoop*(R1/R3) 式2
従って、電流ISはR1とR3とによって確立される比率に基づいてループ電流に比例する。R1とR3との例となる値としては、それぞれ1オームと5000オームとである。このような構成では、ISはループ電流を5000で割ったものに等しくなる。
ILoop*R1=Ib*Rb 式3
ILoop=Ib*Rb/R1 式4
Vout=Ib*RF+Ib*Rb+ILoop*Rf 式5
ここで、式4を式5に代入することで、
Vout=ILoop*(R1/Rb)*(Rf+Rb)+ILoop*Rf 式6
IS=(Vout-Vref)/R3 式7
Vreg=(IS+I5)*R4+Vref 式8
上記式6は、オペアンプ160の出力(Vout)が直接、アダプタを流れる電流ILoopに比例することを示している。ILoopが増加すると、式7に示される関係のように増加するVoutによって、ISが増加する。ISが増加すると、Vrefが定数であるためR5を流れる電流が一定であるので、R4を流れる電流は減少しないといけない。R4を流れる電流が減少すると、R4の両端の電圧が減少し、従ってVregが減少する。このように各式によって、ループ電流が増加するとアダプタループ端子間の電圧(Vreg)が減少することが説明される。
