“…By these algorithms, the CMV is reduced from ± V dc /2 of the conventional space vector PWM (CSVPWM) algorithm to ± V dc /6. However, it can be seen that the output phase current ripple and the DC bus current ripple of the inverter are slightly higher than those of the CSVPWM algorithm via theory, analyses, simulations, and experimental results [11], [13], [14].…”

“…Hence, research has now been focused on the development of various PWM algorithms for the reduction of CMV, known as reduced CMV-PWM (RCMV-PWM) algorithms [7]- [16]. RCMV-PWM algorithms can be divided into three groups: active zero state PWM (AZSPWM) algorithms [7]- [16], remote state PWM (RSPWM) algorithms [14], and near state PWM (NSPWM) algorithms [12], [14], [16]. In addition, the AZSPWM algorithms can be further divided into AZSPWM1 [7]- [14], [16], AZSPWM2 [13]- [15], and AZSPWM3 [8], [13], [14] algorithms.…”

To reduce common-mode voltage (CMV), various reduced CMV pulse width modulation (RCMV-PWM) algorithms have been proposed, including active zero state PWM (AZSPWM) algorithms, remote state PWM (RSPWM) algorithms, and near state PWM (NSPWM) algorithms. Among these algorithms, AZSPWM algorithms can reduce CMV, but they increase the number of switchings compared to the conventional space vector PWM (CSVPWM). This paper presents a new AZSPWM algorithm for reductions in both the CMV and total number of switchings in BLAC motor drives. Since the proposed AZSPWM algorithm uses only active voltage vectors for motor control, it reduces CMV by 1/3 compared to CSVPWM. The proposed AZSPWM algorithm also reduces the total number of switchings compared to existing AZSPWM algorithms by eliminating the switchings required from one sector to the next. The performance of the proposed algorithm is verified by analyses, simulations, and experimental results.

“…With the advancements in the PWM control schemes, the harmonic spectrum of the output voltage can be maneuvered to contain a pronounced fundamental component and to transfer the harmonic energy to the components of higher frequency [2][3]. This is desirable, as it is relatively easier to filter out the components of higher frequency compared to the components of the lower frequency.…”

“…The essential difference between these three SVM strategies is the zero vector synthesis method. The distributions of the zero-voltage space vectors within a cycle period have a significant effect on the line current harmonics, common mode voltage and capacitor current stress, as already exposed in 6-switch PWM rectifiers under normal operation [25]. However, detailed performance analyses and comparisons of the SVM schemes, in terms of the line current distortion, common voltage and capacitor current stress, are still rare regarding post-fault PWM rectifiers.…”

In this paper, some crucial performance characteristics related to the operational reliability of the post-fault Pulse Width Modulated (PWM) rectifiers, such as line current harmonic distortion, Common Mode Voltage (CMV), and current stress on the capacitors, are fully investigated. The aforementioned performance characteristics of post-fault rectifiers are highly dependent on the utilized space vector modulation (SVM) schemes, which are also examined. Detailed analyses of the three most commonly used SVM schemes for post-fault PWM rectifiers are provided, revealing the major differences in terms of the zero vector synthesis approaches. To compare the performances of the three SVM schemes, the operating principles of a post-fault rectifier are presented with various SVM schemes. Using analytical and numerical methods in the time domain, the performances of the line current distortion, common mode voltage and capacitor current are evaluated and compared for each SVM scheme. The proposed analysis demonstrates that the zero vector synthesis approaches of the considered methods have significant impacts on the performance characteristics of rectifiers. In addition, the advantages and disadvantages of the proposed SVM schemes are discussed. The experimental results verify the effectiveness and validity of the proposed analysis.
