【Abstract】 Negative sequence voltage and current of fundamental waves were taken from three-phase asymmetric system with harmonic waves by means of the improved fan-in vector transfer. Introduction was made to the fan-in transfer method without additional delay. Hardware of active power fi lter with TMS320F2812 as the core was designed,main flowchart of the software given. The algorithm with DSP realizing fan-in vector transfer is simple,having very good application perspective.更多还原
