One-Cycle Controlled Active Power Filter Based onLoad Current Derivative Compensation

doi:10.11985/2017.11.006

Abstract

Abstract:

To improving the electric power quality, active power filter (APF) is commonly used. The distorted current, which is produced by non-linear load, has a steep change due to uncontrolled current rectification. Implementing classical one-cycle-control scheme, The dual-polarity modulated Single-phase full-bridge is hardly to gain enough current to compensate the distortion current of non-linear load. The load current derivative compensation scheme is proposed to improve the performance of APF. Theatrical analysis and implement schematic are presented. Using Matlab/Simulink, the result of simulation shows that the total harmonic will greatly reduced.

Key words: Active power filter, single-phase full-bridge converter, one cycle control, load current derivative compensation
