Taking the harmonic elimination of a Copper Foil Company as object of study, the thesis is focused on the application of HAPF (Hybrid Active Power Filter) and expands the hardware design of controller, harmonic detection methods and software design of controller, as well as parameter design. The research of HAPF will also build solid base for its universal application in our country, and accumulate experience for its highvoltage and highpower application. The hardware structure of APF controller based on DSP (Digital Signal processor) has been presented, referring to the research achievement inland and aboard. The realtime performance and reliability, as well as patibility of controller have been analyzed in detail. In order to meet the requirement of deadtime that IPM (Intelligence power module) demands, independent hardware circuit for generating deadtime is designed in this thesis. Harmonic detection is a very important part of APF. Control strategy and performance of APF will be greatly influenced by calculation delay and lowpass filter in many harmonic detection methods. Then an algorithm based on a simplified slidingwindow Fourier is presented in this thesis, which makes calculation of harmonic current in APF simply and detects referenced current effectively. And then, the effectivity and feasibility of this algorithm have been proved in the theory of frequencydomain filter. The software design of controller is divided into menu program and control program. The menu program is posed of the display about realtime voltage wave, current wave, spectrum and control variable。 the control program includes the sampling and signal analysis, the modulation and triggering of signal and the modification of control variable. At last, the thought and realization of system program are formulated in this thesis. With the appliance of HAPF in Jiang Xi Copper Foil Company, the system topology structure, main circuit design, parameters putation and output filter design are discussed. Furthermore, the feasibility of this equipment has been validated by applying effectiveness.
