模块化双向AC/DC变换器并联系统无缝切换控制
Seamless Switching Control for Modular Bi-directional AC/DC Converter Parallel Systems
摘要
Abstract
The issue of inconsistent power flow among modular bi-directional AC/DC converters in parallel operation with the conventional control was analyzed.The inherent relationship between system power flow and the trend of the DC bus voltage was researched and a bi-directional operation control for the modular AC/DC converter parallel system was proposed.The consistent power flow of each module is achieved by utilizing a positive and a negative DC bus voltage regulators.Power flows of rectification and inversion are distinguished naturally with different DC bus voltages,and seamless switching between rectification and inversion was also realized.The stability of the modular AC/DC converter parallel system was analyzed in detail with the design principle of the key parameter given.A prototype system was built and both of the steady-state and dynamic experimental results were presented to verify the effectiveness of the proposed system and control method.关键词
