Abstract :
FREQUENCY CHANGERS have been discussed at various times during the past 20 years.1,2 At the 1944 AIEE summer technical meeting there was presented a thorough analysis of the design and operating characteristics of a new 20,000-kw electronic frequency changer.3–7 Its installation, together with increasing interest in railroad electrification for the immediate postwar period, has resulted in a renewed interest in frequency changers.
