摘要
Abstract
This paper studies a motor drive structure suitable for high voltage.Because of the high DC link voltage,it is difficult to choose a suitable switching device,so the DC side of the inverter is connected in series to the DC bus,thus reducing the DC side voltage of each inverter.The paper analyzes the causes of uneven DC bus voltage on the input end,and puts forward a three-loop control strategy:speed loop,current loop and equalizing loop.The simulation results show that the DC bus capacitor voltage on the input side can be balanced under the condition of balanced load or unbalanced load.关键词
