Abstract
In the aluminum anodic oxidation process, uses the superimposition ponent the pulse power source craft, can enable the aluminum the surface production hard oxide film, the oxide film to have a better corrosion resistance and the anti- attrition ability, also the crack are few. Because in the performance obvious merit, the superimposition direct current pulse power source already widely used in the alumina production craft. In the industrial production, first requests the power source to have to achieve the enough output, can long-term stably reliably move, and can carry on the adjustment to the voltage electric current, the pulse frequency, passes breaks the ratio to be able to adjust revises, the running time can conveniently establish. In satisfies the technical specification in the situation, the operation simple is as far as possible convenient, avoids plex keyboard holding
This design includes main circuit and control circuit two parts. The main circuit including three-phase all controls the leveling circuit, the filter circuit, cuts the wave electric circuit. The control circuit uses insults the positive 16 monolithic integrated circuits to take the control core, the adjustment occupies the spatial ratio, the frequency, and the pulse width adjusts the output voltage. The switch power part selects IGBT.
Key word: Pulse power sourc; Three-phase rectification; Chopping
