concept of transferred impedances, three chapters are devoted to the basic methods of generating high frequency power: arc and spark oscillators, high frequency alternators, and vacuum tubes.
The design of Class B and Class C power amplifiers with tuned loads is treated in a detailed manner with worked out examples to show the steps which are usually followed in a practical design for high frequency heating applications.
Considerable attention is devoted to: the problems of the current distribution in various shaped charges and the power developed in them; the design of work coils, transformers, and feeders for various applications such as surface hardening, melting furnaces, and brazing; and methods of coupling for both induction and dielectric heating.
Power supplies, timing mechanisms, and high frequency measurements of the electric and magnetic variables are discussed descriptively.
A final chapter treats industrial applications and operating problems, with reference to numerous particular processes and pieces of equipment.
Although not evidently intended as an undergraduate text, it is felt that the book could be admirably used for in-service training of engineers in the subject field. Needless to say, it can well serve as a ready reference to practical problems for electrical engineers and physicists who encounter problems in high frequency heating.
