摘要: Single-phase active rectifiers exhibit an inherent strong second-order current harmonic on their dc-link. The latter is often undesirable from a load point of view and therefore chosen to be eliminated. A common method the use resonant passive LC filter tuned at frequency, which increases order system, posing certain difficulties for voltage control design. This paper presents comprehensive analysis dc-link dynamics. equations are linearized by means small variations, respective closed-loop regulator formed utilizing partial state feedback theory pseudocontinuous systems. output fed inner regulator, following well-known cascaded loop method. stability proposed controller validated throughout whole operating regime its robustness against system parameter variations evaluated. comparison with conventional proves advantages utilized theoretical verified simulations as well real-time implementation experimental laboratory setup.
