AC-DC-AC converter with induction machine-modeling and implementation on floating point dsp as a cost effective interface for renewable energy applications

摘要

The paper presents advanced vector control system for ACDC- AC converter operating as grid interface for renewable energy systems. The control method is based on Direct Torque Control with Space Vector Modulation (DTC-SVM) for Machine Side Converter (MSC) and Direct Power Control with Space Vector Modulation (DPCSVM) for Line Side Converter (LSC). The whole control and protection system has been implemented on cost effective floating point DSP microcontroller TMS320F28335. Simulation and experimental results which illustrate steady state and dynamic properties of the developed system obtained from the 3kW laboratory model are given.
