| Abstract |
In this paper the control of a three phase ac-ac matrix converter with sinusoidal input and output waveforms and unity power factor at the input side is presented. The control strategy bas been developed utilising the space vector modulation technique. This approach has the advantage of an immediate comprehension of the switching strategies. The maximum value V3/2 of the voltage transfer ratio is achieved without considering any third harmonic voltage component. The number of switch commutations within a cycle period can be limited utilising an opportune commutation sequence. Furthermore, safe commutation is achieved by current sensing. A numerical simulation of the overall system has been carried out and the numerical results are presented to verify the operating principle. |
