The Mathematic Modeling Method of Modular Multilevel Converter
摘要
Abstract
Modular multilevel converter is a novel topological structure of high voltage direct current,which draws significant attention of academia and industries at home and abroad with its merits that two level voltage source converter can’t assimilate. Proper mathematic modeling can reflect the nature of the system and provide heavily theoretical security for system fault protection,optimization control and system parameters designing. After researching the principle of modular multilevel converter,this paper establishes its corresponding mathe-matic model and derives the analytic expressions of capacitance voltage,upper and lower arm current,phase to phase circulating current.关键词
