3. Key components and technical features 

3.1     Traction level IGBT module

Adopt international high-quality IGBT module.The fourth generation IGBT technology.Switching loss and conduction loss reduced dramatically.Temperature period and power period enhanced dramatically, the lifetime prolongs.Redundancy design of module ensures APF reliable and safety. 

3.2     Power Unit

 It is the core circuits of APF, used for power conversion. Modularized design, all power units have same structure and electrical performances, they can be interchangeable.

4.  Fully digital control system

Adopting Spartan3adsp FPGA chip of Xilinx.Calculate harmonic and reactive power in real time, and then realize dynamic track and compensation.The control system adopts modularized design.
