This paper presents a simplified mathematic model of parallel APF
and an improved method of current control with triangle-wave pulse-width modulation. Compared with traditional method
a value proportional to source voltage is added to the reference voltage
which improves the accuracy of APF output voltage and makes the output current following the reference current precisely. The simulation results show that in two aspects: harmonic compensation and precision of current control
the improved current control method is better than the traditional one.
