What kind of 主词六替换 will be higher(4)
Electrolytic capacitors, aluminum electrolytic capacitors and monolithic gallbladders, which use sulfuric acid to make the insulating medium, large capacity can carry out smaller volumes for the above, and are marked with a + sign, some are marked with a mark, generally do low cross-linking and side-by-side Circuit filter with larger loss meson, integral aluminum electrolytic capacitor, due to the shortcomings of using special materials, the electrolytic performance is better than ordinary, the preferred frequency, but can not do too much capacity, it can be used to accurately circuits, such as oscillators, or timing circuits.

Power Active Filter
When the traditional alternating current-direct current (AC-DC) converter is put into operation, a large amount of harmonic current will be injected into the power grid, which will cause harmonic loss and interference. For example, when uncontrollable rectification is added with capacitor filtering, the third harmonic content on the grid side can reach (70~80)%, and the power factor on the grid side is only 0.5~0.6.
No matter how good the material and production technology process control of the product is, it is necessary to detect the aging of the equipment. Because the incoming inspection of electronic components and transformers is difficult to control, only by improving the aging and high-temperature sampling of the entire batch of power supplies can we detect whether the quality stability and material management of this batch of power supplies have potential safety risks.
