“…(1) It increases the output switching frequency of the converter instead of boosting the switching frequency of an individual Si-based IGBT; (2) It does not require a large number of independent DC voltage sources. Moreover, MMCs have simple structures and flexible configurations, making them more suitable for high-power, high-speed PMSM drive applications than other multilevel converters [19][20][21][22]. However, the submodule capacitor of an MMC may experience significant voltage fluctuations in motor drive applications.…”

Nowadays, high-speed permanent magnet synchronous machines (HSPMSMs) are widely used in high-speed direct-drive applications. Moreover, modular multilevel converters (MMCs) have attracted a lot of attention. In this paper, the mathematical model of the MMC for the HSPMSM was built on high- and low-speed regions, respectively, and the control of each model is completely decoupled. Moreover, energy balance control schemes based on the common mode current injection of the MMC with HSPMSM drive applications have been proposed for high- and low-speed cases, respectively. Based on this model, the controller is proposed for high- and low-speed cases, respectively. Simulation and experiment results indicate that the proposed energy balance control method for an MMC in the high-speed PMSM drive application exhibits significant performance, which can ensure the energy balance of the MMC and eliminate the circulating current of the MMC directly.

“…To cope with those problems, equipping passive LC filters between the inverters and motors is the best trade-off [5][6][7]. LC filters are always used in underwater propulsion devices and super highspeed drives [8,9]. Nevertheless, some other issues are caused by the LC filters, and they have been drawn attention.…”

In some cases, LC filters are installed between the inverters and motors to suppress the adverse effects of pulse width modulation. However, some techniques should be modified, because the mathematical model of the drive system is changed by the LC filter and the sensors on the inverter output cannot measure some necessary variables. In this study, a multipurpose proportional-integral (PI) observer is proposed at first. The type of observer depends on whether the position sensor is equipped. A sliding mode controller for the LC filter based on the observer is presented, therefore improving the dynamic performance. Furthermore, if the position sensor of the rotor is equipped, an open-switch fault diagnostic method is realised by means of the PI observer; if the position sensor is not equipped, the sensorless estimation is realized. The proposed strategies were realised without any additional current/voltage sensors. Experimental results verified the effectiveness of the proposed strategies.
