| Abstract: | A repeated charging and discharging device to test ZnO nonlinear varistor is developed in this paper. The charging technique with L-C constant-current converter is adopted, and the repeated charging and discharging process of the device is controlled by voltage feedback. The control unit is composed of dialer switches, high voltage divider, triggering controller and power SCR. The charging voltage can be preset continuously by the dialer switches. The device has characteristics of high charging efficiency, easy and accurate charging voltage control, strong anti-interference ability to electromagnetic. |
