MLD模型下逆变电路改进型直接功率预测控制
An Improved P-DPC for Inverter Based on MLD Model
摘要
Abstract
This paper builds a mixed logical model for a new inverter,and treats it as a predictive model in order to research the predictive direct power control for inverter.In order to achieve the aviation power supply requirements and reduce the switching losses,the zero vector improves to the original 3+3 voltage vector control sequence method.By calculating the active and reactive components of the output voltage at the next time,the action time of each voltage vector is obtained on the basis of minimizing the objective function value to complete the control of the circuit.The method reduces the output voltage THD,4+4 voltage vector sequence method is good in dynamic and in static characteristics,and stable in switching fre-quency.The result shows that the method is feasible and valid.关键词
