Abstract:
Wireless power transfer (WPT) technology and applications have become popular in recent years. This is a re-emerging technology that allows a convenient, simple, easy use of electrical energy delivery from a power source to an electrical load within a medium distance in the absence of any electrical cord. This paper presents a wireless power transmitter apparatus that has the capability to propagate wirelessly a low voltage to a load coupled at a wireless power receiver output module. The voltage to be transmitted coming from 2.5 ‒ 3.5 V at a maximum current of 2A DC power source. It differs from typical developed wireless power transmission systems which usually transmit high voltage from either DC or AC power sources. The proposed apparatus was developed applying the magnetic induction concept, working at the operating frequency of 110kHz at a maximum transmission distance of about 10mm. Maximum power transfer is achieved at 5W with 5V constant output voltages and the maximum outpu
t current is up to 1.4A. These specifications are suitable for electronic device power charger applications. The experimental results show the developed apparatus has a peak power transfer efficiency of around 70% and complies with the international standard requirement for interoperability.
