چکیده
In this paper the idea of transfer function of a voltage source inverter (VSI) is used for simulation of a static var compensator (SVC) and a parallel active filter (PAF). This concept makes simulation possible for the above-mentioned converters by generally available simulation software such as student version of Pspice. The idea of transfer function (TF) makes it possible simulation of VSI as a macro-model. In this way, it is not necessary to use semi-conductor switches of VSI or their control circuits. This subject decreases the node number of the circuits, the problem of convergence, the excessive run time and the large memory requirement for output file. The PSCAD/EMTDC simulation package is used as a professional simulation package to satisfy the results. In addition, a new control method for switches of PSCAD/EMTDC simulated converters is presented
