چکیده
A new control scheme is presented which provides simultaneous control of the output voltage and the energy storage capacitor voltage in the full-bridge Boost Integrated with Buck RectifiedEnergy storage/Dc-dc converter (full-bridge BIBRED). The new control scheme solves the problem of wide voltage excursions for the energy storage capacitor voltage under variable load conditions. A low frequency, large signal AC equivalent circuit is presented. The steady state governing equations are given. Mode boundaries for correct operation as a high quality rectifier are established. The control circuit used to implement the new control scheme is discussed. Experimental results validate the concept of the new control scheme.

Comparison between Phase-Shift Full-Bridge Converters with Noncoupled and Coupled Current-Doubler Rectifier
This paper presents comparison between phase-shift full-bridge converters with noncoupled and coupled current-doubler rectifier. In high current capability and high step-down voltage conversion, a phase-shift full-bridge converter with a conventional current-doubler rectifier has the common limitations of extremely low duty ratio and high component stresses. To overcome these limitations, a pha...

Linear AC power supplies can be replaced by their nonlinear switching counterparts due to the lower voltage drops and higher efficiency and power density of switching-mode inverters. Multilevel cascaded H-bridge (CHB) converters are the preferred inverter structure because of modular configuration, control, and protection. The output voltage quality in CHB converters depends on the number of ou...
