Discussion on “voltage ratio in synchronous converters, with special reference to the split-pole converter” and on “application of storage-batteries to regulation of alternating-current systems.” Atlantic City, N. J., July 1, 1

P. M. Lincoln: These papers give a much clearer insight into the theory and expected performance of the so-called “split-pole” synchronous converter than anything which has been produced up to date. With these papers before him, the engineer who contemplates using this type of machine is in much better position to judge of its merits than ever before.
