Abstract: A 1 kW grid-connected wireless power transfer(WPT) system integrating LCC-Series (LCC-S) compensation network and interleaved converters at both input and output stages is presented in this paper. This combination achieves excellent voltage regulation and provides high efficiency over a wide range of power levels. An interleaved power factor correction (PFC) boost converter provides high input power quality meeting the IEEE 519 total harmonic distortion (THD) standards while an interleaved buck converter at the output stage minimizes the output current ripple and provides effective battery charging strategy. The constant current/constant voltage (CC/CV) charging scheme is implemented using a single proportional integral (PI) controller. The full analog design and operation reduce costs and improves reliability and noise immunity. Experimental results validate the robust performance of the system, making it suitable for practical applications.

   Design of an Integrated Magnetic Structure for Hybrid IPT Charger to Achieve Misalignment Tolerance and Constant Output Current

Abstract: To address output current fluctuations caused by magnetic coupler mismatches in Inductive Power Transfer (IPT) chargers, a double-D quadrature (Double DDQ) coupler with LCC-S hybrid topology is proposed. This topology combines an LCC compensator (with an inductor and two capacitors) and series capacitors, along with added coupling between primary and secondary circuits. Integrating compensator inductance within the magnetic coupler enhances mismatch tolerance, ensures constant output current, and eliminates extra coils on the PCB, reducing size. This cost-effective approach is ideal for wireless charging of Electric Road Vehicles (ERVs), tolerating coupler mismatches from free movement. The magnetic coupler's performance in ensuring smooth output current under X- and Y-axis misalignments is analysed. A 1-kW prototype validates the design and demonstrates its effectiveness.

   Enhancing Accuracy of a 2MW Power Converter for High-Current Electromagnets
By Jérôme SAVARY, Xavier BONNIN, Gilles LE GODEC [View]
[Download]

Abstract: This paper focuses on designing the so-called NEPTUNE: a high-power (2 MW), high-current (24 kA) multiphase power converter for particle accelerators, with the goal of minimizing load current harmonics using cost-effective components while considering market constraints. In particular, the effects of parasitic resistance and inductance asymmetries, DC-Link perturbations, and associated mitigation strategies are explored. The paper employs analytical studies, simulations, and measurements on a small-scale prototype to validate the proposed solutions.
