الملخص:This paper presents an improved phase-disposition pulse width modulation for the Cascaded Dual-Output Multilevel (CDOM) converter. Additionally, the traditional CDOM converter is modified to be operated with reduced switching components without effecting the system operation. A phase-disposition pulse width modulation is modified for optimal state to operate the converter under minimized average power device switching frequency. A cost function based on hamming distance of the switching states is utilized to control the proposed converter. The performance of the converter is demonstrated and evaluated for common and different frequency outputs using MATLAB simulations. The converter is operational under a wide variety of operation points and the modulation scheme is shown to be effective in significantly reducing the average device switching frequency.
