Product Description
Low-voltage active power filter APF is a new type of power electronic device used to dynamically suppress harmonics and compensate reactive power. It can quickly track and compensate harmonics of different sizes and frequencies. The reason why it is called active is that compared with passive LC filter, APF can only passively absorb harmonics of fixed frequency and size. APF can separate harmonics and reactive power by sampling load current, control and active output current size, frequency and phase, and fast response, offset the corresponding current in the load, to achieve dynamic tracking compensation, but also can complement harmonics and reactive power and imbalance.
Fast response, offset the corresponding current in the load, to achieve a dynamic tracking compensation.
It can make up both harmonics and reactive power and unbalance.
