提出了一种基于级联多电平逆变器的集成分段储能电机驱动系统。提出了在不同运行模式下能源、分段储能和电动机之间的功率分配策略。为满足所提出的配电策略，提出了一种储能设计准则。此外，该储能系统不仅在所有运行模式下实现谐波补偿，而且在加速时提供峰值功率，在减速时吸收再生功率，从而提高了电机驱动系统的能量效率，减小了能源的尺寸。为了在不同的运行模式之间实现平稳的功率转换，并提供准确的速度跟踪，设计了包含分段储能电压平衡控制的自主蓄电控制系统。在实验室搭建了5.5 kw永磁同步电机（PMSM）驱动系统。仿真和实验结果验证了所提出的电机驱动系统的有效性。
This paper presents a cascaded-multilevel-inverter-based motor drive system with integrated segmented energy storage. A power-distribution strategy among the energy source, the segmented energy storage, and the electric motor is proposed under different operation modes. A design guideline for energy storage is provided to meet the proposed power-distribution strategy. Moreover, the energy storage features not only implementing the harmonic compensation in all operating modes but also providing peak power during acceleration and absorbing regenerative power during deceleration, which improves the energy efficiency of the motor drive system and reduces the size of the energy source. An autonomous power regenerative control system including voltage balancing control of segmented energy storage is developed to perform the smooth power transition between different operation modes and provide accurate speed tracking. A 5.5-kW permanent-magnet synchronous motor (PMSM) drive system has been built in the laboratory. Simulation and experimental results are provided to demonstrate the effectiveness of the proposed motor drive system.
