“…• Considering the simple schemes, the spreading effect of RZV and RPP is not important, we notice the coexistence of a continuous part (noise) and a discrete part (power harmonics clustered at the multiples of the switching frequency which is fixed in both cases: RZV and RPP) [9,11,12,17]. In the other side, RSF spreads completely the spectrum into a continuous noise; this allows us to affirm the superiority of this scheme to RZV and RPP.…”

“…Today, permanent magnet (PM) synchronous motors (PMSMs) are the dominant technologies for many applications, including traction [24,25]. High efficiency, high torque density, and desirable wide speed range performance of these motors have made the technology popular among manufacturers [26][27][28].…”

Recent studies show that synchronous reluctance motors (SynRMs) present promising technologies. As a result, research on trending SynRMs drive systems has expanded. This work disseminates the recent developments of design, modeling, and more specifically, control of these motors. Firstly, a brief study of the dominant motor technologies compared to SynRMs is carried out. Secondly, the most prominent motor control methods are studied and classified, which can come in handy for researchers and industries to opt for a proper control method for motor drive systems. Finally, the control strategies for different speed regions of SynRM are studied and the transitions between trajectories are analyzed.

“…Time for zero voltage is randomized to get better result with Direct Torque Control (DTC) for drives [43]. [44][45] SPWM converters have sideband harmonics and carrier acting as source of electromagnetic noise and pollution by common mode and differential mode noise. The Random PWM inverter has low weight, volume, filtering and has better EMI/EMC.…”

“…Three types of random SVPWM are suggested, random zero vector distribution PWM (RZDPWM), random pulse position PWM (RPPPWM) and random switching frequency PWM (RSFPWM) [44]. Mathematically random SVPWM is similar to traditional SVPWM and so existing methods for capacitor voltage balancing can be modified to reduce switching harmonics [45].…”

This paper provides an insight on various random pulse width modulation techniques and their effect on spreading the harmonic spectrum for various applications like drives, hybrid electric vehicles and renewable energy sources, for two level as well as three level inverter. Acoustic noise reduction, electromagnetic interference conducted and torque ripple are obvious advantages of random pulse width modulation (PWM). PWM converters with multilevel topology can meet with global quality standards for power supplies. The random PWM technique provides additional advantages. Among others, it may be implemented to achieve switching loss equalization in power switches for cascaded H-Bridge multilevel inverters. This paper provides in depth understanding for different random PWM techniques and their applications.
