摘要：

An active filter that removes harmonics from the ac line by the injection of pulsewidth modulated (PWM) controlled currents is described. Optimization of these compensating currents is developed for the removal of all harmonic components up to a specified order using a filter that requires no supply other than the line to which it is connected. The required bidirectional power flow in the filter is achieved by establishing an internal inductor current within upper and lower limits by a purely fundamental current flow into the filter from the line. The performance characteristics of the proposed method are investigated by analysis and simulation. Experimental results from a microcomputer controlled model establish the validity of the approach.
