摘 要:A three-phase (3φ)switch-mode rectifier(SMR)constructed using single-phase (1φ) modules ispresented in this paper. The AC sides of three modulesare △-connected, with proper control, good powerquality iu line drawn currents under well-regulatedDC output voltage is obtained. As one module faultoccurs,the proposed 3φSMR becomes *** the worst case, when two constituted 1φmodulesare faulted, the proposed 3φSMR will be operated as1φSMR to continuously supply regulated DC voltageoutput. As to the control aspect, the dynamic model ofthe 3φSMR under nominal operating condition isestimated. And accordingly, a feedback controller isdesigned to meet the given voltage regulation controlspecifications. Then a robust controller is furtherdeveloped to reduce the control performancedegradation due to the changes of operating conditionand number of connected modules.
