提出了一种基于零平均动态方法的交错固定开关频率准滑动控制算法，并将其应用于并联单相逆变器模块化系统的设计。该方法用于三个逆变器的实验室原型，该原型具有嵌入该算法的基于现场可编程门阵列控制的实现，以及用于处理有源逆变器数量的电源管理策略。提供的实验结果说明了交流输出电压调节、不匹配模块之间的平衡均流、交错固定开关频率操作和针对负载变化的鲁棒性以及系统操作期间逆变器激活方面的设计特征。
An interleaving fixed-switching-frequency quasi-sliding control algorithm based on the zero average dynamics approach is reported and applied to the design of a modular system of parallel-connected single-phase inverters. This approach is used in a laboratory prototype of three inverters with field-programmable gate array control-based implementation embedding this algorithm, as well as a power management strategy for handling the number of active inverters. Experimental results are provided to illustrate the design features in terms of AC output voltage regulation, balanced current sharing among mismatched modules, interleaved fixed-switching-frequency operation and robustness with respect to load variations, and inverter activation during system operation.
