ABSTRACT
The Matrix Converter-Induction Generator AC-AC power system architecture is represented as a simplified block diagram in Figure 1. This is an integrated wind-turbine system depicting the power, control and interface sections [1]. In the power area, the supply lines from the grid incorporate an LC-filter to suppress high current spikes on the input side [2]. The Switch Matrix (converter) is connected to the load side, which is an induction
1 INTRODUCTION
The converter has been a fast emerging technology and much research has been done on its prospects of being used in motor drive applications. The Matrix converter has a number of attractive features like sinusoidal input and output currents, unity power factor operation on any load, ability to function in the regenerative mode etc. The overall design is straightforward and compact. Despite all the advantages the Matrix converter possesses in 3-phase AC-to-AC conversion, it still faces severe technical difficulties in its induction into the mainframe applications for motor drives. It has failed to replace the widely accepted and conventionally used converters such as the back-to-back VSI and the CSI. In the past, there have been issues of safe current commutation and complexity of control algorithms which now have been resolved to quite an extent.
