In this paper, the modeling and control of a new three-level single-stage power-factor-corrected (PFC) ac/dc converter is presented. The converter integrates an AC/DC boost PFC converter and a three-level DC/DC converter. An averaged model of the new converter is derived in the paper and used to design a controller that regulates the output voltage in presence of the input voltage variation and load...
This paper proposes one novel sliding mode controller for the Half-bridge converter to reduce the line and load disturbance. Based on the bilinear model of the Half-bridge DC/DC converter, the small signal model and the design consideration of the sliding mode controller for this converter are deduced and presented. The controller is simply implemented in the analog controller board. The validation...
This paper studies a multiple-input dc-dc converter realized from a standard single ended primary inductor converter topology. The proposed configuration allows the integration of different distributed generation sources into a common DC main bus. This work discusses the converter topology, basic dynamic equations, and explains its basic operation. Stability characteristics are also explored with...
With the development of power electronic techniques, more and more attention has been paid to DC power systems. This paper analyzes the load flow issues containing DC/DC converters in a DC power system. The load flow model of DC/DC converters, which considers the power losses and control strategy of the converter, has been presented and integrated into the traditional load flow algorithm by modifying...
