“…The operation of the 2G MB GaN e-FETs, which are suitable for any topology requiring AC-switches, is verified in a hardware prototype, where voltages up to 400 V and currents up to 10 A are continuously switched. These novel devices, in combination with 2/3-PWM, have the potential to significantly enhance the performance of 3-Φ bB CSI systems, ultimately favoring their usage in place of 3-Φ Bb VSI systems; in particular, a 3-Φ bB CSI system, rated for an output power P out = 3.3 kW, is estimated to simultaneously achieve an efficiency η = 98.4% and a volumetric power density ρ = 18 kW/dm 3 Section VI-A is realized as illustrated in Fig. 16(a), (b) and (c).…”

Latest dual-gate (2G) monolithic bidirectional (MB) gallium nitride (GaN) enhancement-mode field effect transistors (e-FETs) enable a performance breakthrough of current DC-link inverters, e.g., in terms of power conversion efficiency, power density, cost and complexity. In fact, a single 2G MB GaN e-FET can replace the two anti-series connected conventional power semiconductors required in this inverter topology, realizing a four-quadrant (AC) switch with bidirectional voltage blocking capability and allowing controlled bidirectional current flow. Furthermore, as shown in this paper in case of three-phase (3-Φ) buck-boost (bB) current source inverter (CSI) systems comprising a DC-link current impressing buck-type DC/DC input stage and a subsequent boost-type 3-Φ current DC-link inverter output stage, a variable DC-link current control strategy, based on aSynergetic Control concept, can be applied to significantly reduce the switching losses occurring in the 3-Φ inverter. This strategy is denominated two-third pulse-width modulation (2/3-PWM), since by properly shaping the DC-link current with the input stage, the desired 3-Φ sinusoidal load phase currents can be generated by switching, in each switching period, only two out of the three phases of the output stage. Based on comprehensive circuit simulations and analytical calculations, a detailed explanation of the developed modulation and control schemes in different operating conditions is provided, and the reduction of losses enabled by 2/3-PWM is confirmed. Next, the seamless transition of the 3-Φ bB CSI system from 2/3-PWM to conventional 3/3-PWM is demonstrated. Finally, a 3.3 kW 3-Φ bB CSI system, applying 2/3-PWM and employing research samples of 2G MB GaN e-FETs in the 3-Φ inverter, is estimated to achieve an efficiency of 98.4% and a power density of 18 kW/dm 3 (295 W/in 3 ) at a switching frequency of 140 kHz.

“…Lowering the electric drives voltages down to 48V standard drastically mitigates electrical hazards, which is of particular benefit to transportation applications. It also significantly reduces the insulation system stress [2] and enables using silicon MOSFETs or wide band-gap technologies, both having low switching and conduction losses [3], [4]. For a given three-phase motor and a given current rating, it is possible to reduce the voltage rating by using several independently supplied winding sets [5].…”

This article addresses the control issue of a structure enabling the segmentation of three-phase electric drives. The proposed segmentation process offers an additional degree of freedom in terms of voltage rating for power electronics but results in a three-phase system with highly coupled sub-windings. Thus, for such a segmented motor, the true challenge lies in controlling the machine global electromagnetic torque while balancing the power among the different inverters. To tackle this issue, the dq standard synchronous frame is extended to common and differential modes. This approach enables to design a suitable control structure based on an analytical model and physical considerations. The developed model is calibrated with realistic numerical values obtained from a finite element analysis. Finally, an experimental setup allows developing a proof of concept which shows the interest of the proposed control method compared to a standard multiple dq-frame method. The key finding is that the above-mentioned control objective of the segmented synchronous motor can be achieved without additional inductors and despite the severe constraint imposed by such highly coupled segmentation.

“…The way to reduce the dv/dt without directly changing the motor structure is to use filters in the motor drive systems [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. Comparisons of the filter performance in Si-insulated gate bipolar transistor (IGBT)-based and SiC MOSFET-based motor drive systems are explained in [13][14][15][16].…”

This paper introduces a gallium nitride (GaN) high electron mobility transistor (HEMT)-based matrix converter for motor friendly drive systems. A fast switching characteristic of the GaN devices causes high dv/dt. This increases the importance of noise immunity and the reduction of parasitic components in system design. In addition, the high dv/dt in motor drive systems leads to voltage spike at a motor input terminal and leakage current through a motor chassis. Accordingly, a gate drive circuit consists of devices with a high common mode transient immunity. A printed circuit board was designed to minimize parasitic inductance, which was analyzed by performing simulations. To mitigate the dv/dt of the voltage applied to the motor and the leakage current, a dv/dt filter and a sine-wave filter were utilized as an output filter of the matrix converter. The effectiveness of each filter was verified by driving an induction motor.
