【摘要】 VIENNA整流器作为一种能量单向流动的三电平升压型AC/DC变换器,广泛应用于电动汽车充电系统等场合。其控制策略的好坏是提升电能质量、增加系统可靠性的关键,因此VIENNA整流器控制策略成为学者们研究的热点,主要分为电流控制、直流电压控制、中点电位平衡控制3个方面,根据这3个方面对VIENNA整流器控制策略进行了分类、归纳和总结,分析了各类控制策略的原理和优缺点,为VIENNA整流器的研究与工程应用提供参考。更多还原

【Abstract】 As a three-level Boost AC/DC converter with unidirectional energy flow,the VIENNA rectifier is widely used in electric vehicle charging systems and other occasions. The key to improve the power quality and the system reliability is the quality of control strategy. Therefore,the control strategy of the VIENNA rectifier has become a hot topic for scholars. The VIENNA rectifier are mainly divided into three aspects:the current control,the DC voltage control,and the midpoint potential balance control. And the control strategies of VIENNA rectifiers were classified and summarized based on the three aspects. The principles,advantages and disadvantages of the various control strategies were analyzed to provide reference for the research and engineering application of VIENNA rectifiers.更多还原
