For a traditional 2-coil system outputting constant voltage (CV), the transfer efficiency decreases drastically as transfer distance increases. To solve this problem, this essay proposes a 3-coil system which could achieve CV output and Zero Phase Angle (ZPA) conditions with specific parameter values. This 3-coil system could partly relief transfer efficiency fall at a long transfer distance, without any complicated controls. In order to achieve CV and ZPA condition, this essay devises the parameter values based on the decoupling 3-coil model, and a prototype is designed accordingly to verify these characteristics. With 10 cm transfer distance, output voltage deviation is 5.5% as the load varies from 12 Ω to 200 Ω, proving that the output voltage almost keeps constant with load change. Furthermore, with software simulation, a comparison experiment between the proposed 3-coil system and a Series-Inductor-Capacitor-Inductor (S-LCL) compensated 2-coil system is built to verify the efficiency improvement. The transfer distance change leads to the differentiation of voltage gain for both 2-coil and 3-coil systems. So, the input voltage for both systems and the compensated capacitor in receiver loop of the 3-coil system are manipulated for keeping 60 V output voltage on the 12 Ω load. With distance increasing from 10 cm to 20 cm, transfer efficiency varies from 92.61 to 48.9% for the 2-coil system, and from 92.89 to 84.26% for the 3-coil system, effectively proving the efficiency improvement. The experiment and simulation results prove the effectiveness of the proposed method.

“…WPT is a promising technology based on electromagnetic theory and radiowave theory, representing the combined application of electrical and radio science [5]. In previous research that applying WPT concept such as electric vehicle charging [6], [7], power transmission system [8], wireless charger for mobile phone [9] shows that the important part of the WPT is the transmitter and the receiver. The function of the transmitter coil is to transfer the current by using magnetic flux to the receiver coil.…”

<span lang="EN-US">This paper presents a battery-less power supply using supercapacitor as energy storage powered by solar. In this study the supercapacitor as energy storage, as opposed to batteries, has widely researched in recent years. Supercapacitors act like other capacitors, but their advantage is having enormous power storage capabilities. Maximum charging voltage and capacitance are two variables of storage in the supercapacitor. The supercapacitor is used as energy storage to charge a low power device wirelessly and act as a power supply. The solar energy is used as a backup power supply if there is no electricity in the remote or isolated area to charge the supercapacitor. The time taken to charge the supercapacitor depend on the amount of current rating of the solar panel. The higher the current, the shorter the time taken to charges the supercapacitor. Power supply using supercapacitor can store up to 30 Vdc using a DC-DC boost converter.</span>

“…Combining two systems of IPT and solar panel is a new idea and few studies have been carried out in this regard. For example, mobile charging with wireless transmission system and solar panel has been simulated for low-power conditions [3]. It has been investigated for home use with focus on how to design the magnetic core [4], and for developing an economic system with low efficiency [5].…”

In this article, Inductive Power Transfer (IPT) system fed by a suggested panel and its various stages of design and analysis are described. Typically, IPT with its separate control system, and solar panel with its separate Maximum power point tracking (MPPT) unit works together to achieve maximum efficiency. This use of two separate converters reduces the efficiency and reliability of the entire system. Therefore, a system is recommended so that while eliminating the MPPT unit and considering design considerations, we can make MPPT function occur in the IPT control circuit. Simulation of the conventional and the proposed system shows that with removal of MPPT, the system efficiency increases from 90% to 93%.
