“…Figure 3). Historically, the DB-VSI originates from high-voltage/power motor drives used in industrial or traction applications (Stemmler and Guggenbach, 1993;Kawabata et al, 1999;Chen et al, 2010;Hatua and Ranganathan, 2011;Han and Ha, 2013) and has been proposed as an alternative to multilevel inverters (Akagi, 2017) In order to integrate the inverter into the compressor housing, the volume of the DB-VSI inverter should be reduced by factor of 2, compared to the state-of-the-art SB-VSI solution. Moreover, the inverter should be able to withstand the high-temperature environment of the motor, which requires a low loss inverter design to limit the temperature gradient between semiconductors and motor/heat sink.…”

Fuel cell technology is continuously gaining ground in E-mobility applications. Fuel cells require a constant supply of pressurized air, for which high-speed turbo compressors with air bearings are an optimal choice to reduce size, guarantee oil-free operation required for the lifetime of the fuel cell, and increase efficiency. However, the inverter driving the electric motor of the turbo compressor does not scale down with increasing speed; therefore, other technology advances are required to achieve an overall compressor system with low weight. New power electronic topologies (double-bridge voltage sources inverter), cutting edge power semiconductor technology (gallium nitride), and multiobjective optimization techniques allow reducing the inverter size, increasing inverter efficiency, and improving the output current quality and in return lowering the losses in the electric motor. This enables the electrical, mechanical, and thermal integration of the inverter into the compressor housing of very high-speed and compact turbo compressors, thereby reducing the size and weight of the overall compressor system by a factor of two. Furthermore, a turbo compressor with an integrated inverter reduces complexity and cost for operators with savings in casing, cables, coolant piping, and connectors and reduces EMI noise by shielding the high-frequency motor currents with one housing. Beside its main application for fuel cell air supply, the advantages gained by an integrated inverter can also be used in other boosting and air handling applications such as advanced air and exhaust handling in combustion engines. The proposed integration concept is verified with a 280,000 rpm, 1 kW turbo compressor, targeted for the Balance of Plant (BoP) of a 5–15 kW fuel cell. The experimental results show that the temperature limits on the power electronics parts can be kept below the limit of 90 °C up to a coolant temperature of 55 °C, and beside the advantage of lower cabling effort, the efficiency of the compressor system (turbo compressor and integrated inverter) is increased by 5.5% compared to a turbo compressor without an integrated inverter.

“…Unlike a structure in which two inverters are applied to the stator side, in a double inverter-fed wound motor (DIFWM), an additional inverter is connected to the rotor windings through slip rings and brushes. Both side inverters provide power for driving the motor [10][11][12][13][14][15][16][17][18][19][20][21][22][23]. The structure of the DIFWM is shown in Figure 1.…”

For efficient operation of the squirrel cage induction motor, the flux must be properly adjusted according to the torque. However, in such variable flux operation, the performance of torque control is limited by the flux control because it is not possible to measure and control the rotor current that affects the flux. On the contrary, in a double inverter-fed wound machine (DIFWM), the inverter is connected to the rotor side, as well as the stator side, and the rotor current can be controlled. This controllability of the rotor currents improves the operation performance of a DIFWM. This article presents the decoupling current control method of a DIFWM for fast flux and torque control. Since the rotor flux is directly calculated by the stator and rotor currents, the bandwidth of the flux control can be improved to the bandwidth of the current controller, which means that the torque control also has the same bandwidth. In this article, a detailed current controller design method with a DIFWM feed-forwarding decoupling method to eliminate all coupling interferences is proposed. The simulation and experimental results regarding the DIFWM are presented to verify the torque and flux control performance of the proposed control method.

Industrial Motor Drives require often required optimal speed and torque control. This work presents the implementation of a eld-oriented control (FOC) with a predictive current control strategy for an induction machine fed by a voltage source inverter. The FOC generates the stator current references for the predictive current controller, which selects the optimal switching state to be applied in the next sample period. The results from a Matlab/Simulink simulation validates the good dynamic performance of the proposed technique, making it a suitable strategy for induction machine control with two-level inverters.
