Abstract: This paper gives a design of a novel withstanding voltage test device in which the test voltage can be adjusted automatically.The high voltage output is adjusted by electromotor controlled by PWM signals.Overvoltage and overcurrent protection are provided by both software and hardware.A RMS-to-DC converter and a high precision ADC are used to get high measuring accuracy.The high voltage adjusting method is improved.

Key words: withstanding voltage test； adjusting voltage automatically； RMS-to-DC converter；
