High-voltage steel-tank mercury-arc rectifier equipments for radio transmitters

The paper deals with steel-tank mercury-arc rectifier equipments developed and built in this country in recent years for the supply of high-voltage direct current for radio transmitters. The arrangements adopted, and the reasons for them, are described in detail; and an account is given of certain problems encountered in the development of these sets. The effect of the circuit adopted on some of the factors affecting backfire at high voltages is briefly discussed.
