This invention addresses inefficiencies in wireless power transfer (WPT) systems by improving AC to DC conversion with power factor correction. It ensures a near-unity power factor with sinusoidal AC line current, offering adjustable output voltage gain. The system operates at a constant frequency, compatible with IC fabrication, reducing electromagnetic interference (EMI) in nearby electronics. Applicable across various WPT applications, it enhances energy efficiency and power transfer capability in short to mid-range systems.
