Abstract
The authors present an active filter comprising a three-phase current source inverter (30 kVA) operating in PWM. Optimal management of switching pattern makes it possible to isolate the three phases and then to achieve an accurate model of the PWM inverter. The regulation takes into account the resonant and very slightly damped output filter. So it allows fast and accurate control of the active filter AC currents to correctly compensate for the nonlinear load harmonic currents. The operation of a protection unit against overvoltages on the DC side of inverter is also described. Experimental results show a satisfactory compensating performance
