A New Electronic Multiplier for Power Frequencies

Abstract

THERE are many electrical applications which require alternating current at higher frequencies than those normally obtained from the power lines. These applications include: induction heating, the operation of high-speed motors, and the operation of fog horns and underwater signaling devices. Although motor generators are satisfactory for most of this work, their inherent upper frequency limitations and need for mechanical maintenance have led to the development of several alternative methods of obtaining higher frequencies.
