Abstract :
The paper discusses the analysis and control of single-phase AC systems by means of rotating frames. Two methods for the D-Q transformation are compared in terms of computational requirements, transient response and sensibility. One of the transformation methods is based on sine and cosine composition, while the other uses a bi-phase transformation. The comparison has been done using simulation and an experimental prototype of a three-level NPC boost rectifier.
