电机控制器直流侧前置Buck/Boost双向变换器的母线电容电流控制策略研究
Research on the Bus Capacitor Current Control Scheme for Buck/Boost Bi-directional Converters in Motor Drive Systems
摘要
Abstract
A bi-directional Buck/Boost converter is placed in the motor drive system, which can regulate the bus voltages for high efficiency and output power. The reason that the traditional control scheme cannot suppress bus voltage fluctuation caused by motor operation state fast switching is analyzed. On this basis, a novel control scheme with bus voltages outer the control loop and bus capacitor currents inner the control loop for the bi-directional Buck/Boost is presented. For the bus capacitor current can not be measured directly, the paper proposes a new capacitor current calculation method. Small-signal model analysis results of the drive system show the proposed scheme in this paper has better performance in voltage fluctuation suppression than the traditional one. Simulation and experimental results have confirmed the correctness of the above theories.关键词
