Abstract:

APF has its outstanding features comparing with PPF, it is a new type harmonic suppression and reactive power compensation device. This paper makes an introduction about two key technologies about APF, and it makes a prediction to the trend of the key technologies. APF is the main harmonic suppression technique at present and in the future. At present, there are large of loads in every industry, such as, electric arc furnace in steel industry, the welder in automotive industry, and these industries are important sectors of the national economy, we can do not stop them running, only installing APF in the appropriate location .Therefore, APF has broad prospects for development in various industries.
