Developing the laboratory models for wireless energy transmission
The increasing use of various electrical devices in home or office, such as mobile phones, laptops, tablets, etc., requires more power and charging cables, creating clutter. Wireless energy transmission technology helps solving this problem. Although wireless energy transmission technology is not a new idea, it has only recently started to develop more intensively. Inductive wireless charging has proven to be the best solution for powering and charging low-power electrical devices over short distances when it comes to wireless power transmission. Inductive wireless energy transmission is divided into two circuits separated by air. In primary circuit the electricity is converted into a variable magnetic field, and in secondary circuit, if located within the reach of the primary circuit, magnetic energy is converted back into electrical energy. This paper describes the principle of inductive wireless energy transmission at a distance, experimentally designed wireless transmission circuits and tests performed by electrical engineering students and professors, using these circuits in the laboratory. Through laboratory exercises, students independently design and connect transmitter and receiver circuits. Furthermore, they investigate how different parameters affect the energy transmission efficiency. By changing the coil parameters (different shapes, diameters, wire thickness, number of turns, inductance), as well as the capacity and frequency, students measure the parameters of the transmitted electricity at different distances of the transmitter and receiver. After completing the exercises, students significantly improved their knowledge in the field of electromagnetic induction and the problem of wireless long-distance transmission of electricity. Exercises are prepared in the laboratories of the University North by students of electrical engineering and adapted for further use as a tool in the teaching of students in next years.
