Control of Single-phase Double Boost Effect AC-DC Converter

This paper investigates the Control Strategy of the Single-phase Unidirectional Double Boost Effect Rectifier. A double closed control loops strategy with a current inner loop and a voltage extern loop is investigated. In order to improve the performances of the single-phase unidirectional VIENNA rectifier, a coil is added in the structure of the converter. The new structure is called “DBE”. These structures operate in continuous current and PFC modes thanks to an AC side current control. An optimal current control strategy is developed based on the use of an analog current controller. This one operates in sliding mode with a control of the maximum switching frequency of the power switches. Experimental results show the accurate tracking of the proposed analog current controller and confirm the advantages of the DBE compared to the single-phase VIENNA. Finally, a DC voltage controller is synthetized based on the power conservation and implemented in a Dspace system. Experimental results highlight the DC voltage control loop
