Simulation Research on Cascaded Multilevel Active Power Filter for Distribution Network
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.
