本文基于三相五电平双变流器应用于感应电机驱动系统的假设，提出了两种控制策略。所提出的控制策略的目的是纠正直流母线电容器的电压不平衡，使输入功率因数保持在接近单位的水平，并实现可调速度驱动。分析了这两种控制策略下变流器的运行特性，并用一台3.7kW的感应电机进行了实验验证。
In this paper, two kinds of control strategies for a three-phase five-level double converter are described on the assumption that the converter is applied to an induction motor drive system. The purposes of the proposed control strategies are to correct voltage imbalance of the DC-bus capacitors, to keep the input power factor at near unity, and to achieve an adjustable-speed drive. Characteristics of the converter operated by each of the two control strategies are examined and the validity is verified by experiments using a 3.7-kW induction motor.
