IMPROVEMENTS TO CURRENT GENERATION AND CONTROL SYSTEMS FOR ELECTROLYTIC

摘要

Two auto-transformers are connected in parallel to the same phase and each is provided with half-wave rectifiers to eliminate negative and positive half-waves respectively. The supply to electrolysis tank consists of AC voltage, symmetrical or asymmetrical as required. The positive and negative half-waves can be controlled by micro-processor, using a programme to adjust automatic regulators on transformers and, where appropriate, to adjust thyristors in the rectifiers to control the conduction angles.
