Abstract
Wireless power transfer (WPT) enables the transmission of electrical energy without physical connections, commonly used in charging devices and electric vehicles. Conventional methods often face limitations including narrow range, inadequacies in energy transfer, and high costs associated with infrastructure. In order to overcome the issues, this research proposes a Bridgeless Power Factor Correction Active Boost Rectifier (PFC-ABR), aimed at enhancing the efficiency of WPT for charging applications. The proposed architecture employs an AC source connected to a source inductance, which transfer power into a Bridgeless PFC-ABR that efficiently converts AC to DC power. The rectified output is processed by a single-phase high-frequency inverter, generating high-frequency AC power that is transmitted wirelessly through an isolation transformer. On the secondary side of the transformer an interleaved synchronous rectifier is provided to obtain a stable DC output, supplying power to the load through a capacitor bank. The experimental results are implemented by using MATLAB SIMULINK software which displays the efficiency as 93% with reduced THD 0.49% along with unity power factor. The proposed framework, demonstrates significant potential towards improving the performance of wireless charging systems, making it highly suitable for future high-efficient and high-power wireless energy applications.
