A Novel design of Capacitive Transformer

Project Abstract / Summary : The proposed micro transformer is based on polarization in dielectrics. It is a low expensive, small, lightweight, coreless, heatless, high efficiency transformer. It has variable output voltages with good current output. It is just like the conventional transformers but the number of windings is less and core is not used. It has only two terminals like diode. The both primary and secondary winding wires are made up of copper and coated by silica dioxide. The area of conductor determines the voltage induction and the dielectric medium determines the current output. Here silica dioxide is used as a dielectric medium because it has good permittivity. In this transformer the electromagnetic field is not created. The novel theory behind it is that wherever an alternating potential presents, a region is developed around it. This phenomenon can be named as Electro Tele Field (ETF). The dipoles are rotated due to the application of alternative voltage. The alternative voltage consists of positive and negative half cycles. During the positive half cycle, dielectric medium is positively polarized, and during the negative half cycle, medium becomes negatively polarized. Hence dipoles get rotated continuously. A continuity tester can detect that field. ETF can flow through conductors and penetrate in insulators. The paper explains the novel effect of alternative voltage on a dielectric medium. The main application is that the emf can be induced from one coil to another coil without electromagnetic field. It is hoped that the micro transformer will make a turning point in transformer usage.


Why did you choose to work on this project topic : An accident made this innovation. one day i bought a continuity tester in front of the television picture tube, then the tester glows without any electrical contact. this incident makes me to do series of experiments on this process. i named it as Electro Tele Field [ETF]. The word Tele indicates television picture tube because very first time, this field was discovered in front of television picture tube so that the field is named as "tele field". At last i could find the reason behind that. By the application of this new theory, A novel core less micro transformer has made successfully.
