Abstract
A solenoid supplied by alternating current (AC) voltage generates electromagnetic which has a field area depends on the level of supplied voltage and current flows through the solenoid. The electromagnetic filed can be captured by the other solenoid in the field area. This concept can be applied in a wireless power transfer (WPT) as presented in this paper. The WPT has transmitter coil and receiver coil which each has form of solenoid. The transmitter coil is connected a half bridge circuit to generate AC voltage on the transmitter coil which transferred to the receiver coil. In the experimental set up, the receiver coil is supplied by DC voltage source and it is changed to observe its effect on the voltage and current on the transmitter and receiver coil of the WPT system.
Highlights
The function of cable as a transmission medium already can be seen in the use of telegrams as a telecommunications medium
The wireless power transfer (WPT) system can be applied in the electrical area, especially in the biomedical device as explained by [19,20,21,22,23,24]. It can be applied as battery charging [25] for DC source of electrical vehicle [26].This paper present the effect of DC voltage source on the voltage and current of 2.5 kHz WPT system
Block diagram of 2.5 kHz wireless power transfer The first concept of 2.5 kHz WPT is an induction process of alternating current (AC) voltage waveform on the side of transmitter coil that produces an electromagnetic field as function of time and induces AC voltage waveform on the side of the receiver coil
Summary
The function of cable as a transmission medium already can be seen in the use of telegrams as a telecommunications medium. The message was encoded into the password morse and translated into electrical signals that are sent through a piece of wire by Morse in the year of 1844 [1, 2]. The working principle of telegram later became the basis of the development of shipping technology information using media cable. Along with the development of technology, the transmission of information in the end can be conducted through the medium of non-cable, called wireless. Wireless communication is done with how to utilize electromagnetic waves as a media delivery information. The electromagnetic waves emitted and captured to processed into useful information
