By choosing proper voltage vector, the common mode voltage could be reduced to one third of voltage of one DC cell by using partial common mode voltage reduce PWM(PCMVPWM), and could be eliminated entirely by using full common mode voltage reduce PWM(FCMVPWM). The relationship between the ...
A simplified space vector approach based active zero state pulsewidth modulation (AZSPWM) algorithms are presented for vector controlled induction motor drive to reduce the common mode voltage variations. The space vector PWM (SVPWM) algorithms divides the zero state time equally between the two zero...

This transformerless inverter suffers from Common Mode Voltage (CMV) and leakage current issues. Furthermore, it has significant switching losses and complex filter designs. The inverter structures and PWM techniques have been modified to mitigate CMV and leakage current. To reduce switching losses and...
NSPWM has low common mode voltage and this results in low common mode current. NSPWM has low switching losses comparable to those of DPWM methods, it has low current ripple compared to the classical methods, and it exhibits no significant overvoltage problems in long cable applications as its...
