“…The voltage boosting and regulation methods are investigated in [16] by adjusting the fundamental phase angle difference between the two inverters and modify the PWM scheme, respectively. To further extend the open-end winding motor speed range, in [17], the flux weakening control by the fully utilization of the main converter is investigated, where the additional voltage boost is also obtained. The fault-tolerant control of the open-end winding motor drive is researched in [18] against the open-circuit fault of the inverter.…”

In order to extend motor operation range, a self-voltage-boosting AC motor drive is proposed in this paper. Compared with the traditional frontend DC-DC converters, the proposed topology reuses the power switches inherently involved within the three-phase inverter without using any additional active components. By modifying the time distribution of the two zero vectors in traditional seven-segment space vector pulse width modulation (SVPWM) technology, the inductor current and the flying capacitor voltage can be adjusted. The proposed topology has the advantage of a wider operating range without extra cost. Moreover, the performance of the motor drive is not affected. Experimental results demonstrate the correctness of the proposed topology. INDEX TERMSInterior permanent magnet synchronous motor (IPMSM), inverter, voltage bootstrap, flying capacitor

“…Consequently, strategies to eliminate ZSC have been proposed in the literature, showcasing the complexity of this configuration [19][20][21][22][23]. On the other hand, the floating capacitor configuration, though eliminating ZSC, exhibits limited fault-tolerance capabilities [24,25].…”

The increasing popularity of electric drives employing an isolated dual-inverter (DI) topology is motivated by their superior DC-link voltage and power utilization, fault-tolerant operation, and potential for multilevel operation. These attributes are significant in battery-powered transportation, such as electric vehicles and aviation. Given the considerable freedom in modulation and control of the DI topology, this paper researches the impact of reference voltage vector distribution between the two individual inverters. The study also evaluates the influence of two well-established asynchronous modulation strategies—Space Vector PWM (SVPWM) and Depenbrock’s Discontinuous Modulation (DPWM1). Since simulation tools nowadays play a crucial role in power electronics design and concept verification, the results are based on extensive and detailed models in Matlab/Simulink. Employing the basic field-oriented control of a 12 kW induction motor with precisely parameterized SiC switching devices for accurate loss calculation, this research reveals the possibility of significant energy savings at multiple operating points. Notably, optimal efficiency is achieved when one inverter operates up to half of the nominal speed while the other solely establishes a neutral point for the winding. Moreover, the results highlight DPWM1 as a superior strategy for the DI topology, showcasing reduced converter losses. Overall, it is shown that the system’s losses can be significantly reduced just by the design of the voltage vector distribution in the drive’s operating range and the modulation strategy selection.
