Dynamic Monitoring of Battery Variables and Mutual Inductance for Primary-Side Control of a Wireless Charging System

IEEE transactions on industrial electronics (1982. Print)
This article proposes a fast and accurate real-time estimation method for developing a dynamic battery circuit model on the primary side of a series–series (SS) compensated wireless power transfer (WPT) system. By detecting the current of the transmitter

Thickness Measurement of Thermal Barrier Coating Based on Mutual Inductance of Eddy Current System

IEEE transactions on industrial electronics (1982. Print)
Thickness of thermal barrier coating (TBC) plays an important role in the insulation property of coating. Eddy current (EC) testing could be used to measure the thickness of ceramic coating (TC) for TBCs.

A Noncommunication Mutual Inductance Estimation Method for Multiple Transmitters SS-Compensated Dynamic Wireless Power Transfer With Low Calculation Effort

IEEE transactions on power electronics
Mutual inductance estimation (MIE) plays an essential role in the primary-side control for dynamic wireless power transfer (DWPT) systems. Traditional MIE method that is only based on primary-side transmitter (Tx) information contributes to no redundant ...

A Dynamic Current Sharing Model of Multichip Parallel SiC MOSFETs Considering Layout-Dominated Mutual Inductance Coupling

IEEE transactions on power electronics
Dynamic current imbalance of parallel SiC mosfets can lead to uneven losses and even thermal runaway. Unbalanced parasitic parameters dominated by layout are one of the main causes of unbalanced dynamic currents.

Mutual Inductance Calculation of Rectangular Coils at Arbitrary Position With Bilateral Finite Magnetic Shields in Wireless Power Transfer Systems

IEEE transactions on power electronics
Horizontal or rotational misalignment between the transmitting and receiving coils with magnetic shielding is inevitable during the wireless charging process, which leads to mutual inductance changes between the coils with magnetic shielding.

Research on Mutual Inductance Identification and Efficiency Optimization of the Three-Coil Wireless Power Transfer Systems With Switchable Relay Coil

IEEE transactions on power electronics
One of the most difficult problems of the three-coil wireless power transfer (WPT) systems is that the receiving coil is hardly fully aligned with the transmitting and relay coils, which affects the efficiency of the practical system seriously as the ...

A Mutual-Inductance-Type Fault Current Limiter in MMC-HVDC Systems

IEEE Transactions on Power Delivery, 2020
Faults on the dc line threaten the stability and reliability of the modular-multilevel-converter-based HVDC (MMC-HVDC) systems. Fault current limiting is one of the crucial steps to handle the dc line fault.
