“…The generated waveform has THD value swaying between 11%-9% subject to vary according to the feedback voltage, during all cases where the harmonic exceded the limits of IEEE 519. However, the performance demonstrate better voltage quality in comparison to [15], [16], [23], [24]. Likewise, the proposed technique is at lower cost in comparison to other advanced technique such as in [25].…”

This paper investigates the <span>low order harmonics of a simplified approach to generate high quality sinusoidal pulse width modulation (SPWM) waveform produced by voltage source inverter (VSI). Programmable interface controllers (PIC) microcontroller was chosen to produce the signals in Real time with voltage feedback to control the puls width during direct current (DC) link voltage reduction. The research considered simplicity, durability, and reliability as conditions. The proposed technique was successfully passed one of the biggest challenges which is time criteria presence due to execution time of the feedback loop and the transient time required </span><span lang="EN-GB">for power electronics switches to turn fully off and on, known as dead time. The proposed technique can be considered as practical, high feasibility according to economic point of view and its accuracy to the input variables. The pseudocode, algorithm, and flowchart for closed loop real time voltage control to produce SPWM system using microcontroller was explained, illustrated and verified. The desired objectives were accomplished to achieve system that is able to generate high quality real-time SPWM with closed loop control.</span>

“…Popular examples include sinusoidal PWM (SPWM), hysteresis PWM, and space-vector PWM (SVPWM). Among them, the SPWM method generates the inverter switching signals by comparing the modulating signals with a common triangular carrier wave, in which the intersection points determine the switching points of the inverter power devices [12,13]. The hysteresis PWM method controls the inverter output currents to track the reference inputs within the hysteresis band, but with various switching frequencies [14,15].…”

This paper presents the design and implementation of an application-specific integrated circuit (ASIC) for a discrete-time current control and space-vector pulse-width modulation (SVPWM) with asymmetric five-segment switching scheme for AC motor drives. As compared to a conventional three-phase symmetric seven-segment switching SVPWM scheme, the proposed method involves five-segment two-phase switching in each switching period, so the inverter switching times and power loss can be reduced by 33%. In addition, the produced PWM signal is asymmetric with respect to the center-symmetric triangular carrier wave, and the voltage command signal from the discrete-time current control output can be given in each half period of the PWM switching time interval, hence increasing the system bandwidth and allowing the motor drive system with better dynamic response. For the verification of the proposed SVPWM modulation scheme, the current control function in the stationary reference frame is also included in the design of the ASIC. The design is firstly verified by using PSIM simulation tool. Then, a DE0-nano field programmable gate array (FPGA) control board is employed to drive a 300W permanent-magnet synchronous motor (PMSM) for the experimental verification of the ASIC.
