In this paper, the stability of the buck-boost dc-dc converter in the continuous conduction mode (CCM) is investigated by using a modeling method. The proposed method is based on the two Laplace and Z-transforms. The Laplace transform is used for determination of the general relations of the inductor current and the output voltage. Also the Z-transform is used for obtaining the transfer function of...
Recent development of power electronics introduces the use of flexible ac transmission systems (FACTS) controllers in power systems. These devices are helping to performance of power system especially when power system supports unbalanced loads. One of the most important of FACTS devices is unified power flow controller based on matrix converter (UPFC-MC) which space vector modulation (SVM) technique...
One of the most effective Flexible AC Transmission Systems (FACTS) that was used in power system, is the unified power flow controller (UPFC). In this paper, the modeling of a new structure of UPFC based on indirect matrix converter (UPFC-IMC) that is controlled by space vector modulation (SVM), is developed to consider of dynamic studies of power system. Through the presented modeling, the transient...
