Abstract :
This paper investigates a three-level three-leg dc-link converter for ac to ac single-phase to single-phase conversion. PWM methods, which are based on per-phase and space-vector approaches, extends the concept of local and general apportioning factor. A control strategy for applications in which the input and output frequency are equal, in order to obtain the maximum utilization of the dc-link voltage, is also presented. Experimental and simulated results are presented.
