Abstract

This paper proposes a new strategy for harmonic filtering of a three-phase shunt active filter system. The shunt harmonic filter's control objective is defined as: balance the phase angle of the input current with the phase angle of the line frequency component of the load current. This objective is achieved in digital implementation without sensing the input voltages. The controller uses a phase-shifting method on the sensed input current and then applies the resistor-emulator-type input-current-shaping strategy on the phase-shifted current. In implementation, Texas Instrument's digital-signal-processor-based unit TMS320F240 EVM is used as the digital hardware platform. The control algorithm is computationally simple yet the harmonic filtering performance is high. The analysis, simulation, and experimental results of a three-phase shunt active filter prototype on a 25-A nonlinear load are presented.
