High time-stability performance of the injection kicker system is important for the Beijing Electron Positron Collider Upgrade Project (BEPC II), with jitter and drift less than +/- 5ns. In order to compensate the delay time drift of thyratron on the kicker pulsed power supply, a drift stabilizer is developed. The test results meet the demand of design by regulation resolution=1ns, jitter+drift < 2ns in 8 hours. The detailed design of the time-drift stabilizer will be described in this paper.
