Pulse-Frequency Converter Development and Modeling within MATLAB/SIMULINK Environment

The article is devoted on modeling semiconductor converter scheme of the pulse-frequency converter (PFC) with four-powered keys on turn-on SCR thyristors. The PFC scheme has been modeled within MATLAB environment by means of Simulink/Simscape library components. Operation principle of the PFC was defined. Square-ware generator have been modeled via Simscape library elements. The experiment was carried out and the adjustment and output characteristics of the PFC have been obtained. The analysis of the characteristics obtained during modeling and experiment were carried out. The adequacy of the developed PFC model was confirmed.
