For the same system parameters, the proposed control technique provides better voltage boost across the Z-source capacitor, DC-link, and also the AC output voltage than the traditional PWM. The ripples in the Z-network elements are found to be reduced by 75% in the proposed modulation scheme with optimum harmonic profile in the AC output. Since the Z-network requirement will be based on the ripple profile of the elements, the Z-network requirements can be greatly reduced. The effectiveness of the proposed modulation scheme has been simulated in Matlab/Simulink software and the results are validated by the experiment in the laboratory. 2014-02-20T13:45:04Z 2014-02-20T13:45:04Z 2012-04 Article International Journal of Automation and Computing, vol. 9(2), 2012, pages 200-210 1476-8186 http://link.springer.com/article/10.1007%2Fs11633-012-0634-4 http://dspace.unimap.edu.my:80/dspace/handle/123456789/32065 en Springer Verlag |
