    Bipolar Duty Cycle Control for Dual Side LCC Compensated Inductive Power Transfer System for Wide Output Voltage Range
    (IEEE Computer Society, 2024) Kishan, D.; Chub, A.; Vinod, M.
    This paper proposes a hybrid phase shift control strategy for dual side inductor-capacitor-capacitor compensated inductive power transfer (IPT) system to achieve a wide output voltage regulation range. The first-order harmonic time domain model is used to compute the inverter output voltage. Then, models of system operation in constant voltage (CV) and constant current (CC) modes are developed to analyze the efficiency of the battery charging process. The designed controller loops are validated for a 1 kW MATLAB Simulink model. Results show that a maximum efficiency of 93.80% is achieved at full load conditions, and the proposed control strategy achieves zero voltage switching (ZVS) in more switches than the conventional control method. © 2024 IEEE.

    Design of a Multi-Mode DC-DC Converter for High-Power Wireless Charging of Electric Vehicles
    (Institute of Electrical and Electronics Engineers Inc., 2024) Kishan, D.; Mallikarjuna, B.; Ahmad, M.W.; Chub, A.
    The design of high-power wireless power transfer (WPT) systems has been the subject of substantial research due to the increasing demand for fast, efficient, and effective battery charging methods for electric vehicle (EV) customers. This paper proposes a DC-DC converter capable of operating in three distinct modes. It incorporates an H6-Bridge inverter, which can be configured as half bridge-half bridge (HB-HB), half bridge-full bridge (HB-FB), and full bridge-full bridge (FB-FB), and is connected through LCC-Series networks to a dedicated H6-Bridge configuration. This innovative design enables efficient charging of EVs with battery voltage classes ranging from 400V to 800V without affecting the current ratings of the converter's components. Furthermore, the paper presents an analysis of an equivalent circuit WPT system for battery packs with output voltages of 400V, 600V, and 800V. To validate its effectiveness, a 7.2 kW power converter with a 600V input and a variable output range from 400V to 800V was simulated, achieving an impressive maximum efficiency of 94.2% across a wide spectrum of output voltages. © 2024 IEEE.

    Optimized LCC-Series Resonant DC-DC Converter for Efficient Inductive Charging of EV's with 400V and 800V Battery Systems
    (Institute of Electrical and Electronics Engineers Inc., 2025) Kishan, D.
    With the prevalence of electric vehicles (EVs) equipped with batteries rated at either 400 or 800 volts, the design of wireless inductive charging infrastructure poses a significant challenge. Conventional approaches rely on DC-DC converters at the receiver end to regulate voltage, leading to increased circuit complexity, added weight on the vehicle, and decreased overall efficiency. In response, this paper proposes a novel solution: a resonant converter located at the transmitter side capable of doubling the voltage to accommodate both 400 V and 800 V EV batteries. This innovative approach not only maintains high power transfer efficiency during charging but also eliminates the need for additional onboard circuitry. Moreover, the receiver system utilizes only passive semiconductor devices, enhancing compatibility and efficiency across a range of battery voltages. Additionally, the paper explores the advantages of incorporating LCC-series compensation into this converter. © 2025 IEEE.
