Abstract
En 中文
Optimized pulse pattern, a powerful technique to address harmonic issues for power converters at low switching frequencies, has been widely recognized in high power applications in both industry and academia. However, existing solutions primarily focus on the optimization of single converter scenarios. In this work, we propose a global-synchronized optimized pulse pattern technique for power converter clusters. As an upper-layer optimization strategy, the proposal utilizes the additional switching pattern freedom provided by the neighboring power converters and achieves extreme power quality at the common interface, even with ultra-low switching frequencies. Moreover, a pattern extension mechanism is designed to ensure sustained synchronization among units throughout the optimization interval, releasing the inherent computational challenge in the optimization problem. Experimental data confirm its effectiveness.
