摘要

级联h桥多电平有源整流器是一种突出的变换器结构。它具有引人注目的优势,包括许多应用的高可调节性,例如固态变压器,牵引应用,中大功率电机驱动器和电池充电器。然而,当h桥在不平衡负载和不对称电压条件下运行时,设计先进的控制策略以保持系统的稳定性变得非常重要。本文提出了一种基于李雅普诺夫函数的控制方法来控制单相级联h桥有源整流器,使其达到全局渐近稳定。在传统的基于李雅普诺夫函数的稳定控制方法中加入电容电压反馈以减小LCL滤波器的谐振。此外,采用比例谐振(PR)控制方法获得参考电流信号。这增加了当前控制方案的鲁棒性。采用直流电压平衡控制程序防止h桥间直流电压不平衡。直流电压通过PI控制器控制。通过仿真和实验验证了该控制方法的有效性。

A Control Scheme Based on Lyapunov Function for Cascaded H-Bridge Multilevel Active Rectifiers
The cascaded H-bridge multilevel active rectifier is a prominent converter configuration. It presents compelling advantages, including high adjustability for a number of applications, such as in solid-state transformers, traction applications, medium and high power motor drives and battery chargers. However, when the H-bridge is operating under an unbalanced load and asymmetrical voltage conditions, it becomes important to design advanced control strategies to maintain the stability of the system. In this study, a Lyapunov-function based control method is proposed for controlling the single-phase cascaded H-bridge active rectifier to achieve global asymptotic stability. A capacitor voltage feedback is added to the conventional Lyapunov-function based stabilizing control method to minimize the resonance of the LCL filter. Additionally, a Proportional-Resonant (PR) control approach is adopted to obtain the reference current signal. This increases the robustness of the current control scheme. A DC voltage balancing control procedure is also employed to prevent the unbalanced DC voltage conditions among the H-bridges. The DC voltage is controlled via a PI controller. The capability of the control approach is verified with simulation and experimental studies.
