Matrix- Converter (AC/AC)
Sparse Matrix ConverterThe Sparse Matrix Converter is a new kind of AC/AC converter with a reduced number of components and a modulation scheme of low complexity and realization effort, avoiding the multi-step commutation procedure of the conventional matrix converter which could impair the system reliability for operation in industrial environment.
Drag the time-marker (vertical red line) in one of the two time-behavior applets with the mouse.
The actual sectors, which are defined by the combinations of signs of the input phase voltages and/or
of the output phase voltage fundamentals are marked in yellow and are numbered (there are 12 different
sectors for the input and output quantities). The respective switching signals within one switching
period and the DC link voltage uZK and the DC link current iZK are shown in the pulse interval applet
