Due to increasingly demand of power in each area, power cut is regular phenomena. Even an interruption for few cycles of power supply, results in losses of data storage, mal functioning of various sensitive equipments. Various methods have been reported in literatures to provide continuous power supply such as uninterrupted power supply, battery system and others non conventional source of energy...
This paper discusses a novel high-efficiency interleaving push-pull converter with very low input voltage and high output voltage. Such push-pull converter should be used as high capacity battery discharger, and has the capability to feedback the discharging energy to the grid if it is cascaded with an inverter. The main characteristics of such push-pull converter are high voltage turns ratio, all...
This paper proposed a high-efficiency battery charging and discharging system for high-capacity single-body Li-ion battery. This system can work as battery formation system or battery test system. The main system structure includes a single-phase bi-directional PWM rectifier, dc-link, half-bridge converter with current-doubler synchronous rectifier as charging unit and interleaved pull-push converter...
A dynamic charge equalization scheme of series battery packs using multiple-winding transformer is presented in this paper. The proposed cell to cell type balancing control scheme is designed to be many bidirectional forward converter operated at discontinuous inductor current model for reducing the switching loss. Simulation and experimental results show that the proposed battery equalization scheme...
