  E-Dri­ven method is a tech­ni­cal backup for positron source for ILC. In the positron source, the positron is gen­er­ated and ac­cel­er­ated in a multi-bunch for­mat with gaps in a macro-pulse. We em­ploy AM (Am­pli­tude Mod­u­la­tion) to sup­press the tran­sient beam-load­ing, but a small fluc­tu­a­tion is still ex­pected, de­pend­ing on the com­pen­sa­tion ac­cu­racy. In this ar­ti­cle, the positron yield which is ratio of num­bers of positrons over elec­trons, is eval­u­ated as a func­tion of the com­pen­sa­tion ac­cu­racy. With this re­sult and the de­tail in­ves­ti­ga­tion of the beam load­ing com­pen­sa­tion ac­cu­racy by AM, the positron yield of E-Dri­ven Positron source for ILC is eval­u­ated.
