WORKING PRINCIPAL: The slayer exciter is a high voltage stepup transformer, with an output voltage high enough to create such an electric field, which lightens up the fluorescent bulb. How does it work:
Turning the circuit on, R drives the base of the transistor Q Q turns on and drives current into the primary of the transformer. The current is limited by the limited available base current. The created magnetic field drives the secondary of the transformer. The secondary voltage wants to grows large. But the tiny stray capacitance on the output resists the change, although very small, against the rise of the output end and so in return the voltage on the other end of the transformer goes down, pulling the base of the transistor low. Diode D prevents the base voltage to fall more than 0.7V below ground, which in return pushes the output end of the secondary high. The transistor turns off and so the magnetic field starts to reduce. The base voltage rises again and Q turns on and the cycle repeats.
Result: Whenever we bring a fluorscent bulb close to the secondary winding, after switching on the circuit, 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, over a distance, without usage of wires or cables. The key parameter in transmitting power is efficiency. Conventional methods of transmitting power don’t have high capacity of transmitting energy with less power loss. Long range communication is possible which is impossible with conventional method, is achieved with this technology.
Doing this project we conclude that with the help of this kind of technology, 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. It is envisaged
that wireless energy would be really accomplished with the advantage of easy implementation and cost effective i.e., cost of transmission and distribution overhead would become less. In the long run, this could reduce our society’s dependence on batteries, which are currently heavy and expensive.
WIRES… A BURDEN!!!
FUTURE WORK: Wireless electricity transmission can change the world of electricity and electrical engineering. The power loss due to transmission lines can be reduced(no I square R loss). Less amount of wires would be used in any circuit.
