Voltage control of mercury-arc rectifiers

THE mercury-arc rectifier competes with the older well-established types of apparatus, the synchronous converter and motor generator set. Both of these types of apparatus are flexible in application as they may be adjusted through a range of different output characteristics and in the case of the booster-type converter and motor generator set, considerable range in voltage control is possible. In order to take full advantage of the desirable features of the mercury-arc rectifier, its output voltage should duplicate that of its rivals.
