Abstract :
Modeling and control design issues of parallel three-phase PWM boost rectifiers in DC distributed power systems are presented. Small-signal characteristics of parallel modules are investigated in comparison with those of a single module. With distributed DC bus impedance included, a master/slave control scheme is adopted to ensure load sharing. The system stability based on loop-gain analysis is discussed. The interaction possibilities are presented briefly. Simulation results with frequency domain and time domain are demonstrated
