Wireless Power Transfer (WPT) is an enabling technology for the mass deployment of Electric Vehicles (EVs) as it minimizes driver intervention during the charging process. Major challenges of WPT systems include coil misalignment and large air-gap, as both degrade efficiency. To address these issues, a vertically-mounted compact dual-coil charging pad for reduced air-gap is presented in this thesis. A linear-slider-mounted transmitter pad allows for lateral self-alignment using two integrated electromagnetic coils. Due to parking accuracy, the vertically-mounted charging pads increase variation in the air-gap, which degrades the electromagnetic coil operation. A position-correcting control algorithm that detects the system impedance and resonant frequency is proposed for improved pad alignment. An experimental prototype achieves a peak DC-DC efficiency of 90.1%. The charging pads laterally align in 1.75s and correct misalignments as large as 240mm. The control algorithm is successfully demonstrated with the pads being corrected to within 10mm of perfect alignment.
