This paper proposes a novel phase-shift dual full-bridge converter with shared leading leg and dual outputs in series. Full soft-switching range of the active switches can be achieved based on the parallel full-bridge configuration of the converter, and the dual outputs of the proposed converter are connected in series. The output voltage can be regulated by primary-side phase-shift and secondary-side...
The energy storage devices are necessary to the stand alone PV generation system. Lead acid battery which performance is specially designed is suitable for PV generation application. The battery charging and discharging control with the max power of PV array is the key point to increase efficiency of the generation system. In this paper, the new system configuration with parallel battery charger is...
The rapid development of digital control technology provides a new approach to applications of modern control theory and algorithm in power supplies. Firstly, the paper presents a digital DC/DC converter regulated by a fixed-structure variable-parameter PID (proportional-Integral-differential) controller and analyzes the limitations if a large signal disturbs the system; secondly, the feasibility...
