| Abstract: | The method of applying cascaded multilevel topology to active power filter is studied.Carrier phase shifting PWM is adopted,and the simple PI controller is used to control the output current of APF.Simulation result demonstrated that APF based on cascaded multilevel topology could trace and compensate the grid harmonics acc-urately,and good dynamic response and high detection accuracy are approached.Furthermore,DC capacitors voltage of each link could be balanced fast and accurately.The application of APF in high voltage field is expanded. |
