“…Assuming that the communication delays are known, the equivalent load resistance R * L can be found from the mechanical output command P * m and the dc-link voltage reference V * dc by using Eq. (8). In practice, the efficiency parameters of the motor and inverter must be taken into account, and thus, preparing a map to determine the equivalent load resistance from the motor's angular speed and torque command would be a workable solution.…”

“…The equivalent load resistance decreases as the mechanical output increases, is essentially consistent with Eq. (8). Because the equivalent load resistance becomes too large in the region with small required power, an upper limit was imposed: the margin of d exceeds its set value but power transfer is not degraded.…”

SUMMARYThe in-wheel motor (IWM) is the most preferred driving mechanism of electric vehicles for its advantages of vehicle motion control, energy efficiency, and vehicle design flexibility. One of the technical problems of the IWM is the reliability of power and the signal wires. Wireless power transfer technology is the best solution to this problem. In this paper, a bidirectional wireless power transfer circuit using a primary inverter and a secondary converter is proposed. We propose a control method for both the inverter and the converter to stabilize the secondary dc-link voltage. The proposed method is verified by simulation and experiment using simulated test equipment. C⃝

In this paper, fault tolerant topologies based on permanent magnet synchronous machines (PMSM) are presented. A numerical model for the simulation of the operational behaviour under normal and fault conditions is developed and validated by test bench measurements. For different fault tolerant topologies, control strategies for normal and post-fault operation are presented and validated by measurements and simulations. In post-fault operation, the presented control-strategies allow the compensation of braking torques and to avoid overvoltages at the machine terminals. In normal operation, the additional degrees of freedom are utilized to improve operational behaviour in various aspects

In electric vehicles, systems with distributed low voltage batteries and DC bus voltage below 60 V could be an alternative to systems with a single high voltage battery. In this work, different low voltage DC-AC inverter topologies are investigated and compared in terms of power losses and component requirements. For a given driving cycle of an electric vehicle the operating points and the required size of the system components are calculated by using an iterative method. This will be used to estimate and to compare the motor losses (by using a characteristic map of the motor) and the DC-AC inverter losses (based on a loss and thermal model of the switches) for each inverter topology. Finally, the simulation is performed and the results are compared with each other. It turns out that the system with a bidirectional DC-DC converter with controlled DC-link voltage inverter has the best performance.
