Abstract

The line commutated inverter with GTO forced commutation is described in this paper. The presented circuit has one bypass GTO inserted in DC power side line commutated thyristor inverter. The extended commutation region with additional one GTO-commutation is clearly shown. Also, a new PWM pattern is presented to decrease the effects of harmonics for commutation. A criterion for designing the AC filter parameters to decrease harmonics of AC part is given. The simulation and experimental results clearly show that the proposed circuit can be adapted in the application of regeneration.
