Sažetak
Sinusoidal active front end is used to achieve the controllable dc voltage at the output with the sinusoidal input current at unity power factor. In the real system supply voltage always contains lower harmonics, most commonly the 5th and the 7th harmonic. Therefore an analysis of the sinusoidal active front end under the power supply distortion here is presented. At the core of this paper is the performance of the synchronous PI current controller both during transients and in steady state operation. Simulation model of the sinusoidal active front end was made in MATLAB/SIMULINK environment and its accuracy was verified comparing the simulation and experimental results. The control algorithm was implemented on the experimental rig, using dSPACE controller.
