SYSTEM FOR GENERATING AND AUTOCONTROLLING THE VOLTAGE OR CURRENT WAVE FORM APPLICABLE TO PROCESSES FOR THE ELECTROLYTIC COLOURING OF ANODIZED ALUMINIUM |
摘要 |
<p>A system for generating and autocontrolling the voltage or current wave form in a process for the electrolytic colouring of anodized aluminium includes feeding power from a source of symmetrical direct current, with a neutral connection directly coupled to a load, while the positive and negative voltages supplied by the source pass through a power control stage which is controlled by a bipolar operational amplifier. The bipolar operational amplifier has two signal inputs, a positive or noninverting input which is connected to a signal generator, and a negative or inverting input having a signal which corresponds to the signal which actually exists on the electrodes of the electrolytic bath. This signal is processed in a half-wave outer controller which is controlled by a programming system.</p> |
