Abstract

In this study, a new control algorithm for three-phase shunt active power filter (APF) is proposed without load and filter current measurement. The proposed control method, based on instantaneous reactive power (IRP) theory, requires only measuring the source currents in order to reduce the number of current sensors (CSs) required in the conventional control approach. The source currents are exactly in phase with the line voltages and approximately sinusoidal waveform after compensation. The proposed control technique has been simulated Matlab/Simulink and tested under thyristor bridge rectifier load condition, and validated with a 10 kVA/380 V experimental prototype based on digital signal processor (DSP) TMS320F2812. Both simulation and experimental test results demonstrate viability of the proposed method, successful in meeting the IEEE 519-1992 recommended harmonic standard limits
