Why Pulse Rectifiers?

We use Oil Cooled Hexa Phase Silicon Rectifiers with Inter Phase Transformers for Nickel and Hard Chrome Plating. Now people are talking on Pulse Rectifier. What is the difference between Pulse rectifier and our present Rectifier. What all are the advantages if we go for Pulse Rectifier. Is it reliable in the range of 12V 750 Amps to Approximately 5000 Amps.

I will be pleased if anybody can advise me in this regard.

A. Hi, Job. Pulse rectifiers are used to do pulse plating. If you wish to do pulse plating they are required; if you do not do pulse plating then they add no value.

Pulse plating means to apply the current in pulses as opposed to smooth continuous DC power. Pulse plating is reputed to deliver some advantages in some circumstances, but is not widely used for nickel chrome plating -- and it adds another variable that you must tame. If you consider yourselves a state-of-the-art, upscale, leading-edge solutions provider you may wish to do some research and development in pulse plating. If you are a typical production nickel-chrome plating shop you do not need pulse rectifiers.

A. Hi, Alan. I don't know what you mean by "AG stage", but a good reference on pulse plating is Leaman & Puippe's Theory and Practice of Pulse Plating [adv. this book on eBay, Amazon, or AbeBooks] if you can find a copy.
