This paper surveys the reduced common-mode voltage pulsewidth modulation (RCMV-PWM) methods for three-phase voltage-source inverters, investigates their performance characteristics, and provides a comparison with the standard PWM methods. PWM methods are reviewed, and their pulse patterns and common-mode voltage (CMV) patterns are illustrated. The inverter input and output current ripple characteristics and output voltage linearity characteristics of each PWM method are thoroughly investigated by analytical methods, simulations, and experiments. The research results illustrate the advantages and disadvantages of the considered methods, and suggest the utilization of the near-state PWM and active zero state PWM1 methods as overall superior methods. The paper aids in the selection an application of appropriate PWM methods in inverter drives with low CMV requirements.

Performance analysis and comparison of reduced common mode voltage PWM and standard PWM techniques for three-phase voltage source inverters Un, E; Hava, Ahmet Masum (2006-03-23) This paper investigates the performance characteristics of the reduced common mode voltage (RCMV) PWM methods for three phase voltage source inverters and provides a comparison with the standard PWM methods. PWM methods are reviewed and their pulse patterns and common mode voltage patterns illustrated. The AC output current ripple, DC link input current ripple, and output voltage linearity characteristics of each modulation method are thoroughly investigated by analytical methods and simulations. The analys...
Common-Mode Voltage Reduction Pulsewidth Modulation Techniques for Three-Phase Grid-Connected Converters Hou, Chung-Chuan; Shih, Chih-Chung; Cheng, Po-Tai; Hava, Ahmet Masum (2013-04-01) This paper experimentally investigates the performance of three-phase voltage source pulsewidth modulation (PWM) converter, with the grid interfaced photovoltaic energy conversion system being the main application. In such applications the ground leakage current [common mode current (CMC)] should be much less than an ampere and this is difficult to obtain in transformerless (direct) connected systems. With the target being the reduction of the common mode voltage (CMV) and CMC, the converter performance is ...
Performance characteristics of the reduced common mode voltage Near State PWM method Un, Emre; Hava, Ahmet Masum (2007-09-05) The Near State PWM (NSPWM) method, which has low common mode voltage/current is proposed for three-phase voltage source inverter drives. The method is described and its voltage linearity, output current ripple, DC bus current ripple, common mode voltage and output line-to-line pulse patterns are thoroughly studied and compared with classical PWM methods. The theory, simulation, and laboratory experiments illustrate that NSPWM has low common mode voltage, results in less common mode current, has low switchin...
Implementation of 1 kV on LV feeders: a smart alternative to MV line investments to solve voltage drop problems at LV systems OZENA, Kadir; CEBECI, Mahmut E.; TOR, Osman B.; BATAR, Gokhan; KILIC, Andac; TURKMEN, Ulfet; Güven, Ali Nezih (2017-04-21) This paper presents methodology and on-site pilot implementation of utilizing 1 kV at low voltage (LV) feeders as an alternative to medium voltage (MV) line investments to solve voltage drop problems at LV systems. Typically distribution companies solve voltage drop problems of LV system by installing a new MV/LV transformer and transferring outmost loads of the existing transformer to the new transformer. This necessitates installation of MV line between the existing and new transformer. The implementation...
