This paper presents a characteristic comparison between a five-leg inverter and a nine-switch inverter. The five-leg inverter and the nine-switch inverter is a single inverter that can drive two AC motors independently. Concretely, we show a circuit architecture of both inverters, a modulation method for an independent drives and a division of voltage utility factor. Moreover, investigate about the...
Recently, the five-leg inverter, with which we are able to control two AC motors independently, is suggested. This inverter has five legs, so we make space for one leg compared with using two three-leg inverters. In this paper, the method of independent vector control of driving two permanent magnet synchronous motors (PMSMs) is described. Although it is difficult to drive two PMSMs in parallel with...
This paper presents an improved method of voltage utility factor from 50% to 86.6% for a five-leg inverter when two induction motors are driven in vector control and in a condition that a frequency of two motors isn't extremely different, and the improved method of voltage utility factor is theoretically shown. The five-leg inverter is a single inverter that can drive two motors independently and...
