Film Capacitor Pulse Energizing Method

Abstract

The present invention discloses a thin film capacitor pulse enabling method. According to the method, pre-enabling processing is performed on the alternating-current voltage of a thin film capacitor. An alternating-current voltage pre-enabling processing process includes the following steps that: S1, first pulse voltage is applied to the thin film capacitor, so that enabling can be carried out, and discharging is carried out on the thin film capacitor, and the value of the first pulse voltage ranges from 50 to 200 V; and S2, when the total time value of the enabling and discharging of the thin film capacitor is smaller than a preset processing time value t, the step S1 is repeated, and when the total time value of the enabling and discharging of the thin film capacitor achieves the time value t, alternating-current voltage pre-enabling processing is terminated. According to the thin film capacitor pulse enabling method of the invention, an alternating-current voltage pre-enabling process is additionally adopted in an existing thin film capacitor pulse enabling method, the alternating-current voltage pre-enabling process specifically includes the steps of low-voltage enabling for the thin film capacitor and discharging of the thin film capacitor, and therefore, the self-healing point of a metal thin film can be decreased, and 80 to 90% of the loss of the metal thin film can be deceased, and the capacitance of the thin film capacitor can be ensured.

However, when the above-mentioned self-healing repairs the metal film, the area of ​​the metal film removed is relatively large, resulting in a large loss of the metal film, which in turn leads to a decrease in the capacitance of the film capacitor.
