This paper presents a novel perspective to understand different winding configurations of even and odd number of rotor pole flux-switching permanent magnet machines. A simple analytical method is used for the calculation of total offset angle of flux linkages by taking into account an offset angle of stator slot and rotor poles. The 12-slot/10-pole and 12-slot/13-pole flux-switching permanent magnet machines are conceptually segregated into two sets of 6-slot/10-pole and 6-slot/13-pole machines, respectively. This is used to address even harmonic elimination and winding configuration properties in even and an odd number of rotor pole configurations. Finite element analysis also verifies the concept.

For automotive applications, accurate torque production capability and high efficiency of the traction motor is very important. However, the performance of widely used interior permanent magnet (IPM) machines is influenced by temperature variations, and temperature variations of the magnets in automotive applications can be profound. In this paper, the state-of-the-art torque compensation control methods of IPM machines in the literature are reviewed. The methods for torque error estimation due to temperature variation are classified. In addition, the methods for adjusting the operating points of IPM machines to maintain torque production accuracy and high-efficiency operation are also overviewed. The advantages and disadvantages of each algorithm are described and compared in detail. This paper facilitates the development of high performance and robust IPM machine drive systems for the automotive industry.

This paper introduces a Zero First-order (or Fundamental-harmonic) Ripple (ZFR) drive topology for Switched Reluctance Machines (SRM). The proposed drive topology utilizes ripple canceling techniques to eliminate first order ripples on SRM phase currents. This paper will first introduce the proposed ZFR drive topology. Then a Least-Quadratic Regulator (LQR) controller is proposed to utilize the ZFR topology in an optimal fashion. Experimental results are provided to demonstrate the effectiveness of the proposed drive technique.

The nonlinear one-cycle control(OCC) method is adapted to switched-capacitor converter in this paper. To illustrate, the circuit model of dual-phase unity gain switched-capacitor converter is explored, which is organically combined with the OCC control technique. Consequently, a new control loop is formulated and implemented with a simple analog circuit. The model derivation and control loop analysis are all investigated. Experiments results demonstrate that, in wide operation range, the rejection to external disturbance can be completed through one switching cycle. The OCC control can be used for general step-up and step-down dual-phase switched-capacitor converters.

Power electronics engineers typically address nonlinear behavior in switching power converters. It is often desirable to determine when the system operates periodically. The objective of this paper is to study how to set the parameters of the current controller for optimal dynamic behavior while ensuring a fixed frequency operation. The authors investigate a proposed continuous-time averaging model for a PWM current controller based on a modulated hysteresis controller. Stability analysis of the controlled system is performed using the eigenvalues of the system. Simulation and experimental results are presented to validate the proposed approach.

In this paper, wireless power transfer for mobile phones via coupled magnetic resonance with multiple transmitters (Txs) and / or receivers (Rxs) are investigated and tested. The system is able to charge cellphones with more than 3 W in a distance between 5 and 15 cm and also in different angles. The resonant frequency is 6MHz. For lower charging powers the distance between the Tx and Rx can go up to 20 cm. Additionally, the three-dimensional movement of the Rx and its effect to the charging power is tested, as self-rotation and rotation around the Tx coil. This achievement is significant to improve user experience of wireless charging for portable electronic devices.

This paper presents a novel topology, based on inductive power transfer (IPT) that is suitable for dynamic charging of electric vehicles (EVs). The proposed topology is novel in that a super capacitor (SC) is used in conjunction with the EV IPT secondary converter to combine power transfer and energy storage in a single converter. In comparison to existing dynamic EV IPT systems, this topology requires no additional switching components, while offering the benefit of a SC energy buffer. Operational modes of the system are described in terms of the switching waveforms required to transfer energy between the grid powered primary IPT pad and the EV. A mathematical model that describes the power transfer within the system is presented along with a simple control strategy to regulate power flow. Simulated and experimental performance of a small scale prototype system in a typical dynamic charging scenario is presented to confirm the validity of the mathematical model and the control strategy.

The paper presents the characteristics of the latest commercial 1200V 300A SiC MOSFET module and compares it's performance with Si IGBT with the same rating using experimental results and the saber software environment. Our SiC MOSFET model in SABER gives accurate results across a wide range of temperatures. The results show that the 1200V SiC MOSFET has faster switching speed and significantly less switching loss compared to the Si IGBT. Moreover, the Si IGBT switching loss will increase significantly for higher operation temperature, while the SiC MOSFET switching loss has little variation over different temperatures. This paper will also investigates the stray inductance effect on the gate, drain, and source side and verifies its performance with Si IGBT. The double pulse test circuit has been implemented in SABER to simulate the dynamic losses and a brief review of the various applications for automotive industry of the SiC MOSFET has been also presented in the paper.
