Abstract :
One solution for high current applications consists of paralleling power stages of lower power. This paper analyzes and justifies the selection of the PWM algorithm used within interleaved three-phase power inverters with respect to the resulting phase current harmonics, DC link current harmonics, neutral point voltage and inter-converter circulation currents. Analytical aspects of different current control structures used within interleaved power electronics systems and effects of selecting various PWM algorithms are revealed. Finally, analysis of the DSP implementation for different practical solutions is shown.
