| Abstract |
The PWM rectifier investigated in this paper operates as a rectifier to supply DC power to its own
load and at the same time, operates as an active power filter to supply to the AC line a compensating
current to eliminate or reduce the harmonic current produced by a nonlinear load connected to the
same AC line. Simulation analysis of this PWM rectifier is carried out in detail. Introducing a
modulation ratio of PWM, the limit of harmonic compensation by the PWM rectifier is analyzed for
two types of nonlinear loads. It is then shown that the total harmonic distortion of AC supply current
after harmonic compensation is improved greatly compared to that before harmonic compensation.
The influence of the active filtering operation of the PWM rectifier on the ripple factor of its DC
output voltage is also clarified. Experimental results are included to confirm the validity of the
simulation analysis. |
