This paper is focused on the improvement of the control range of matrix converters operating with nonunity input power factor. The analysis leads to the determination in closed form of a modulation strategy that allows increasing the maximum output voltage compared to the traditional strategies under the same operating conditions. The improvement of the control range is made possible by the information provided by the measurement of load currents, which is usually available in electric drives. The feasibility of the new strategy is verified by computer simulations and experimental tests. © 2013 IEEE.

Abstract
This paper is focused on the improvement of the control range of matrix converters operating with nonunity input power factor. The analysis leads to the determination in closed form of a modulation strategy that allows increasing the maximum output voltage compared to the traditional strategies under the same operating conditions. The improvement of the control range is made possible by the information provided by the measurement of load currents, which is usually available in electric drives. The feasibility of the new strategy is verified by computer simulations and experimental tests. © 2013 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
