Carrier Comparison PWM for Voltage Control of Vienna Rectifier [PDF]

open access: yesJournal of the Korea Academia-Industrial Cooperation Society, 2011
본 논문에서는 비엔나 정류기의 전압제어를 위한 반송파 비교 PWM 방법에 대하여 논한다. 일반적으로 산업용 및 통신용 등 여러 응용분야에서 2레벨 정류기가 주로 사용되어 왔다. 하지만 2레벨 정류기는 효율을 높이고, THD를 낮추는데 한계가 있기 때문에 3레벨 정류기에 대한 연구가 진행 되어 왔다. 3레벨 정류기의 대표적인 회로가 비엔나 정류기이다. 기존의 비엔나 정류기는 대부분 전압 명령으로부터 인가 공간전압 벡터를 선택하고, 공간전압 벡터 인가시간을 직접 계산하여, 그 시간동안 전압 명령을 인가하는 공간 전압 변조 방식이 사용된다.

Hybrid Modulation Strategy for the Vienna Rectifier [PDF]

open access: yesIEEE Transactions on Power Electronics, 2021
The Vienna rectifier can produce three voltage levels, however only the connection to the neutral-point is fully controllable using the bidirectional switches. When the neutral-point voltage is not imposed in a phase-leg, the polarity of the pulses generated depends on the diode that is conducting in that phase-leg, which is defined by the current ...
