We briefly introduce the source and harm of aircraft grid harmonic and summarise the common methods of harmonic reduction, such as passive filter, multi-pulse rectifier, power factor correction and active power filter. Then we introduce the disadvantages of the above methods, analyse the application status, advantages and deficiencies of active power filter in aircraft grid harmonic reduction, propose future research orientation of it. This paper is useful for relevant researchers who are engaged in airplane electric design
