“…Efficiency is defined in the following form: η(%)= ( P tot -P condloss -P swtloss P tot ) *100 (10) where Ptot is the inverter total power. Hence, PLECS calculates the conduction and switching losses based on the previous equations and the lookup tables for the semiconductor devices.…”

“…Modulation techniques must be applied to the inverter in order to feed the multi-phase machines and obtain the best performance. Carrier-based PWM (CBPWM) and Space Vector PWM (SVPWM) are the most commonly used modulation techniques for these applications [10]- [13]. Each of the modulation techniques can provide different performance to our system in terms of, for example, distributing and reducing power losses, reducing of the common-mode voltage (CMV), harmonic content, current, and voltage waveform.…”

This paper presents the design and structure of a versatile workbench simulator for evaluating the performance of a five-phase inverter and Permanent Magnet assisted Synchronous Reluctance Motor (PMa-SynRM). The simulator allows for adding variations to the modulation techniques, changing the inverter structure's semiconductor device, and calculating the inverter's power losses. It can also facilitate observing the current, voltage, and the joint temperature of the semiconductors devices. Furthermore, we can obtain a perform that is close to an actual PMa-SynRM, depending on the desired conditions of speed and torque. The workbench simulator was developed by combining three software: Matlab/Simulink, PLECS and Altair Flux.

This paper presents a comprehensive analysis of SVPWM for a five-phase VSI based on SiC devices applied to motor drives. The modulation techniques analyzed use medium and large vectors to reach the reference vector. The 2L SVPWM uses two large space vectors, and the generated output signal contain low frequency harmonics. 2L+2M SVPWM uses two large and two medium space vectors. This technique provides good power loss distribution. 4L SVPWM works with the activation of four large space vectors. This modulation is able to generate low common-mode voltage. The performance and main features are analyzed using Matlab/Simulink and PLECS blockset software. Power losses, total harmonic distortion and common-mode voltage are compared and evaluated.

“…Hence for higher phase number systems the best PWM strategy appears to be pure sinusoidal PWM. Discontinuous modulation is less advantageous for multiphase systems than for three-phase systems [57,62,66] and, for phase numbers above nine, any advantages over the continuous PWM methods disappear [57].…”

“…A study of current ripple rms squared and current THD for discontinuous PWM technique is reported in [66] for the five-phase drive system using the polygon approach. The study relates to two different selections of the active space vectors that can be used in the PWM process, with the conclusion that the standard choice of two large and two medium is the best and that discontinuous PWM only improves the switching characteristics at rather high modulation indices (above 0.8).…”

AbstractMultiphase variable-speed drives and generation systems (systems with more than three phases) have become one of the mainstream research areas during the last decade. The main driving forces are the specific applications, predominantly related to the green agenda, such as electric and hybrid electric vehicles, locomotive traction, ship propulsion, 'more-electric' aircraft, remote offshore wind farms for electric energy generation, and general high-power industrial applications. As a result, produced body of significant work is substantial, making it impossible to review all the major developments in a single paper. This paper therefore surveys the recent progress in two specific areas associated with multiphase systems, namely power electronic supply control and innovative ways of using the additional degrees of freedom in multiphase machines for various nontraditional purposes.Index TermsMultiphase variable-speed drives, ac-ac converters, inverters, PWM, multiphase power electronics, integrated on-board battery chargers.
