TAILIEUCHUNG - Electrolytic capacitors play

The origin of the electrolytic capacitor or condenser can be traced to the second half of the 19th century when the discovery was made (Wheatstone, Buff, Ducretet) that a film can be formed on aluminum electrochemically and that it will exhibit unidirectional electrical conductance and other peculiar properties. One of the early attempted applications of the electrolytic capacitor was in conjunction with the starting of single-phase induction motors; efforts were also made to utilize it for power factor correction in alternating current circuits. It appears that no extensive use had been made of this device until the early twenties, when its utility in filter circuits supplying rectified plate current to. | THE ELECTROLYTIC CAPẮCITOR by ALEXANDER M. GEORGIEV Member American Institute of Electrical Engineers This is a practical book which will be of value not only to engineers concerned with the actual design and manufacture of electrolytic capacitors annual production now amounts to tens of millions but also to that larger group of engineers technicians and maintenance men concerned with equipment in which electrolytic capacitors are used . radio receivers and transmitters sound systems and other electronic apparatus telephone circuits electric welding equipment ond single-phase induction motors such as those used in refrigerators air-conditioning units pumps oil burners washing machines etc. It will also be a useful reference book for academic and industrial research workers in the electrical and electrochemical field and physicists and chemists may find of interest the recorded observations and experimental data on electrolytic cells. The author s primary objective is to describe the design construction manufacture function and testing of dry and wet electrolytic capacitors to explain the operating characteristics of various types and to indicate both their useful applications and their limitations.
