“…A phase opposition disposition (POD) and in phase disposition (IPD) control system comparison was analyzed for the control of the THD in output voltage and current for three-level five-phase inverters [24]. A new switch ladder topology has been presented to evaluate the performance level using symmetric and asymmetric sources for five-phase multilevel inverter drive [25,26]. For threestage t-type neutral point clamped (NPC), three-phase inverters using SVPWM [27], and three level NPC five-phase inverters, simulation and experimental analysis have been presented to minimize the typical mode voltage using redundant switching state voltage vectors [28].…”

To supply five-phase variable speed drives, five-phase voltage source inverters are used. Some of the applications of five-phase variable speed drives are traction, electric & hybrid-electric vehicles, and ship propulsion. Different control systems are available for the controlled output of the five-phase VSI, but space vector pulse width modulation is popular because of its simpler digital implementation. In this paper, the SVPWM schemes have proposed and analyzed for the multilevel operation of a five-phase dual voltage source inverter. The proposed techniques do not contribute a voltage balancing issues such as in multilevel neutral point clamped (NPC) inverters. The author analyzed the performance of five-phase VSI based on THD and fundamental components. Matlab/Simulink model has provided for results verification.

“…The switching pattern of the 6L method uses the outer vectors, which minimize the switching event number. If the vector group chosen is 9, 10, 1, 2, 3, and 4, as illustrated in Figure 4, the corresponding large-vector duty cycles in the α-β plane are as follows [41]: The current sector for a reference voltage of magnitude 𝑉 * and angle Ɵ is given by Equation (18), where the ceil function rounds numbers towards positive infinity to the closest integer and the angle Ɵ lies between 0 and 2𝜋.…”

Multiphase drives have received a lot of interest because of their several features over traditional three-phase systems for high-power applications. Pulse-width modulation (PWM) approaches are necessary to regulate the supply for multiphase ac drives. As a result, it is vital to continually improve the modulation and control approaches used to upgrade output power converters’ quality. This paper offers a comparative analysis of the 2L + 2M and 6L space vector pulse-width modulation (SVPWM) techniques applied to a five-phase two-level voltage source inverter (VSI) fed an inductive (R-L) load. The comparative evaluation is based on measuring the inverter switching losses, the total harmonic distortion (THD) values, and the common mode voltage (CMV) under different operation scenarios. A system model is carried out by MATLAB/Simulink. An experimental prototype is constructed in the lab to validate the theoretical analysis. Simulation results for the system based on the two SVPWM techniques are obtained at different modulation indices and different output frequencies and are confirmed by the experimental results. It has been found that the peak-to-peak CMV of the 6L method is 80% lower than that of the 2L + 2M method. Moreover, 6L SVPWM offers better DC-link utilization compared to 2L + 2M SVPWM.

This paper proposes pulse width modulation schemes for a two-level five-phase voltage source inverter. According to the literature, the generation of a pure sinusoidal waveform requires an (n-1) number of vectors for 'n' number of phases, so in a five-phase system, a minimum of four-vectors is needed to generate a sinusoidal waveform. The author uses only two large vectors in this paper for a five-phase voltage source inverter. Vector diagram, switching table, and switching waveform have presented for two adjacent large space vectors. The performance for each PWM scheme is analyze based on fundamental components and total harmonic distortion. In last, results have verified in the Simulink environment.
