MINI TESLA COIL: high frequency electromagnetic field even from a low voltage DC source. Slayer exciter is simplest version of tesla coil as slayer exciter requires only some basic .Introduction: A Tesla Coil is a circuit that generates a high voltage. components(transistor. . a primary coil and a secondary coil) and also it is does not produce much heat because it consumes less power.resistor. PVC PIPE (12CM).3mm). D=. . RESISTANCE – 22K OHM. CELL – 9V. Transistor – 2N2222A. 3. CONNECTING WIRE. 6. 4. ENAMELED COPPER WIRE(L=20 M. KEY. 7. 2. 5.TOOLS USED: 1. WORKING PRINCIPAL: The slayer exciter is a high voltage stepup transformer. How does it work: Ckt. which lightens up the fluorescent bulb. with an output voltage high enough to create such an electric field. Diagram . 3. The secondary voltage wants to grows large. Turning the circuit on. pulling the base of the transistor low. which in return pushes the output end of the secondary high. Diode D prevents the base voltage to fall more than 0. But the tiny stray capacitance on the output resists the change. 4. . 6. against the rise of the output end and so in return the voltage on the other end of the transformer goes down. although very small. Q turns on and drives current into the primary of the transformer. R drives the base of the transistor Q 2.1. The transistor turns off and so the magnetic field starts to reduce. The current is limited by the limited available base current. 5. The base voltage rises again and Q turns on and the cycle repeats. 7. The created magnetic field drives the secondary of the transformer.7V below ground. Block diagram: . Circuit diagram: . without usage of wires or cables. is achieved with this technology. after switching on the circuit. Conventional methods of transmitting power don’t have high capacity of transmitting energy with less power loss. Result: Whenever we bring a fluorscent bulb close to the secondary winding. The key parameter in transmitting power is efficiency. Long range communication is possible which is impossible with conventional method. over a distance. Conclusion: . The bulb glows producing high intensity light as bulb glows when supplied ac power. It is the transmission of electrical energy from power source to electric load. Doing this project we conclude that with the help of this kind of technology. this could reduce our society’s dependence on batteries.. It is envisaged that wireless energy would be really accomplished with the advantage of easy implementation and cost effective i.e. In the long run. which are currently heavy and expensive. WIRES… A BURDEN!!! . cost of transmission and distribution overhead would become less. wireless power transmission can be made possible and this technology will help us in eradicating the hazardous uses of electrical wires and Huge power losses in transmission. FUTURE WORK: Wireless electricity transmission can change the world of electricity and electrical engineering. Less amount of wires would be used in any circuit. The power loss due to transmission lines can be reduced(no I square R loss). .
