| Abstract |
In this paper the design and testing of a matrix converter using a new method of vector
overmodulation is described. The selection of the bi-directional switches as a main part of the
converter is discussed and an overview of admissible commutation switching sequences is given. The
theoretical output voltage limit which is 86.6% of the input voltage on sinusoidal operation can be
increased up to 105%. Using overmodulation means to stress the grid and the load with non
sinusoidal currents for higher voltage transfer ratio. |
