Electromagnetic System Design of an Inductive Wireless AC Source

Mark Angelo R. Asayas, Ruel R. Cabuyao, and Sigrid S. Luna, “Electromagnetic System Design of an Inductive Wireless AC Source”, Unpublished project paper for the Degree Bachelor of Science in Electrical Engineering, College of Engineering, Manuel S. Enverga University Foundation, March 2015. The usage of electricity is increasing its demands, but some places cannot provide electricity because of some problems, like in one island or remote areas, because of their distance from electricity providers sometimes transmission lines or Grid Corporation cannot provide and also to help environment to re-used busted fluorescent lamps. By those problems researchers try to give solutions using research method of an inductive wireless ac source transmission to give knowledge that industries can provide electricity by means of electromagnetic induction theories and re-used busted fluorescent lamps. The focus on how the system design will produce, by the LC circuit the researchers identify and fabricate the prototype and evaluate the results. The researchers has designed a transmitter which compose of power supply, super capacitor, spark gap and an air-core transformer, this is the AC source that produces electromagnetic field with high resonance frequency and a receiver side where compose of coil and a half-wave rectifier to turn the AC input, into DC output. The researchers found out that the voltage captured by the receiver is inversely proportional to the distance and directly proportional to the transmitter output and the proponents also found out that busted fluorescent lamp can be lighten up because of the high resonance frequency that produce by the Inductive Wireless AC Source.
