Abstract: DT 97-9 International IöR Rectifier Design Tip for SAFEIR™ QU/£T#J?™Series Used in High Frequency Welding Applications By Ugo Robino arid Alberto Guerra Topics covered: The Problem Customer Solution The Efficiency Improvement Benefits 1. THE PROBLEM The HP welding equipment manufacturers are , possible, even higher. The output rectifier stage is a major contributor of the overall system efficiency. The total welding current is "rectified" by the center tap cell in the output stage, and then the ... OCR Scan

Abstract: suppression. The typical symptom is random "tack" welding of the normally-open contacts when switching an , anode). B. A reverse-biased rectifier diode in series with a zener diode such that their anodes (or cathodes) are common and the rectifier prevents normal current flow. C. A metal-oxide-varistor (MOV). D. A reversed-biased rectifier diode in series with a resistor. E. A resistor, when conditions permit its use, is often the most economical suppression. F A reversed-biased rectifier diode. . G. A ...
