“…The efficiency can also be maximized for resonance frequency mismatch [14] or estimated using numerical and circuit models [15]. Multicoil systems have been also proposed in [16,17] to extend the transmission region and thus overcome the problem of the misalignment between the GA and VA coils, which can lead to severe components stress and disturbances [18][19][20], besides hazard magnetic fields [21,22]. However, when referring to automotive apparatuses, the size and weight of the components are fundamental parameters that have to be minimized.…”

This paper analyzes two different design procedures for a series-parallel compensated WPT battery charger, based on different definitions of the operating resonant frequency in the condition of maximum link efficiency. The behaviour of the voltage gain magnitude and the input impedance angle of the resulting WPT links is studied for different loads and coupling coefficients. The design algorithms are supported by analytical formulas derived from an exact circuit analysis of the WPT link, avoiding approximations as far as possible. To support the theoretical approach a case study is proposed, in which both design procedures are implemented considering specifications in line with the actual automotive standards. To conclude, a characterization of the efficiency in both cases is derived.

“…Moreover, the proposed method is verified in the vector control system. The vector control system in the fault diagnosis, which affects the amplitudes of the identified fault symptoms, is assumed in a few reports [13,21,22,26]. The inverter-fed electric drive control system often uses FPGA and a microprocessor, along with the supply voltage vector generation method, for ADC/DAC converter handling, state variable estimation and control system variable calculation.…”

This paper presents the theoretical analysis and experimental verification of a direct fault harmonic identification approach in a converter-fed electric drive for automated diagnosis purposes. On the basis of the analytical model of the proposed real-time direct fault diagnosis, the fault-related harmonic component is calculated using recursive DFT (RDFT) and Goertzel DFT (GDFT), applied instead of the full spectrum calculations required in the most popular FFT algorithm. The simulation model of an inverter sensorlessly controlled induction motor drive is linked with the induction machine rotor fault model for testing the sensitivity of the GDFT- and RDFT-based fault diagnosis to state variable estimation errors. According to the presented simulation results, the accuracy of the direct identification of a fault-related harmonic is sensitive to the quality of fault harmonic frequency estimation. The sensitivity analysis with respect to RDFT and GDFT algorithms is included. Based on the experimental setup with a sensorlessly controlled induction motor drive with the investigated rotor fault, fault diagnosis algorithms were implemented in the microprocessor by integration with the control system in one microcontroller and experimentally verified. The RDFT and GDFT approach has shown accurate and fast direct automated fault identification at a significantly decreased number of arithmetical operations in the microcontroller, which is convenient for the frequency-domain fault diagnosis in electric drives and supports fault-tolerant control system implementation.
