| Abstract |
In this study, the simulation and analysis of a three-phase cycloconverter is achieved by employing two modelling techniques. In the first method the SCR is represented by a L,R,Uo model. In the second, a simple switch model is used. For both techniques, the non-sinusoidal load current is considered and, performance values are computed for various output frequencies and lagging load angles. Later, the analysis is extended covering the non-sinusoidal input voltage case and, performance values are compared with those of sinusoidal input voltages. Input power filter is added into the model and the same analysis technique is employed. The effect of the filter is evaluated by computing and comparing the input current harmonics. |
