The design of compensation transformer parameters plays a key role in the filtering effects of the system of active power filter based on fundamental magnetic flux compensation. The influence on system voltage, current amplitude and harmonic caused by compensation transformer＇s magnetizing inductance and leakage inductance is studied through theoretical derivation and simulation, and the result shows that the parameters of compensation transformer have complex effects on the system. However, the design of active power filter can be optimized through simulation and experiment, which provides a theoretical basis for the engineering design. Finally, a semi physical real-time experiment platform based on RT-LAB is built to verify the feasibility of fundamental magnetic flux compensation filter and the effects of compensation transformer, parameters on the system.
