PROJECT TITLE :

Research on Linear Output Voltage Transfer Ratio for Ultrasparse Matrix Converter

ABSTRACT:

Several existing analysis works of ultrasparse matrix converter (USMC) show that the maximum linear output voltage transfer ratio (MLO-VTR) is less than 0.86half-dozen, however, this paper proves that based mostly on house vector modulation, MLO-VTR for USMC will break the ultimate worth. First, based on the condition that input power factor is one, the most output voltage at intervals one carrier amount and the most linear output voltage are derived. More, the mathematical equations among MLO-VTR, the output/input frequency ratios, and therefore the output voltage initial phase also are derived. Once that, by solving the operating limits of the mathematical relationship of the MLO-VTR, we can get the most value of MLO-VTR beneath different output/input frequency ratios that will be a lot of than 0.86six. Finally, all of theoretical derivations are verified by experiments.
