Description

technical field [0001] The invention relates to a power supply, in particular to a low-voltage high-power power supply for electronic aluminum foil corrosion. Background technique [0002] In the process of forming low-voltage aluminum electrolytic capacitors into aluminum foil, it involves the surface frequency conversion hole layout process of low-voltage anode foil for aluminum electrolytic capacitors. In this process, it is necessary to carry out routine degreasing and oxide film removal on the aluminum surface, and then conduct alternating current frequency conversion hole corrosion. The optimal power frequency for corrosion is 10Hz-45Hz. The current low-voltage frequency conversion technology is mainly used in low-power and low-frequency power supplies, and the power required for electronic aluminum foil corrosion is low-voltage and high-power power supplies. Moreover, since the corrosion of electronic aluminum foil is a chemical process, this highly corrosive chemica...
