Design of sealed ignitron rectifiers for three-wife service

IN the past four years, the many constructional and operational advantages of sealed ignitron rectifiers have greatly aided the war effort by saving critical materials and manufacturing facilities. Two-wire sealed ignitron rectifiers¹ have met industry´s urgent need for efficient d-c power and have found wide application in the range of 75- to 1,000-kw capacity, at voltages ranging between 250 and 600 volts direct current for general industrial, railway, mining, and-electrochemical service.
