Recently multilevel inverter technology has been a very important alternative in the applications which requires multiple separated DC voltage sources such as solar and fuel cells. But as the number of levels and switching devices which must be used increase circuit becomes more open to faults. Furthermore the complexity of both the circuit and the control method rises. In this paper an improved cascaded...
This paper is concerned with the design and simulation of a pulse width modulation (PWM) rectifier for three-phase Permanent Magnetic motor drive. Based on the mathematical model of PWM rectifier, the dual-close-loop engineering design with decoupled feed-forward control is applied in the 3-phase voltage source rectifier. The objective to be reached is to realize unity power factor at the input ac...
