A Direct Power Control Scheme for Bi-directional Buck/Boost Converters in Motor Drive Systems
摘要
Abstract
The DC bus voltage fluctuation suppression in the motor drive system with a bi-directional Buck/Boost converter was studied. The disadvantage that the power feed-forward control scheme cannot effectively suppress bus voltage fluctuation was analyzed. A novel direct power control scheme with bus capacitor energy outer control loop and output power inner control loop for the bi-directional Buck/Boost converter was presented. Moreover, in order to improve the dynamic response of converters, a feed-forward term which reflects the changing trends of output power was added on its duty cycle calculation node. The essential difference between the above two control schemes was compared. Results and simulations of the small-signal model analysis and experimental results show the direct power control scheme has good performance in voltage fluctuation suppression.关键词
