In series-connected battery systems, typically, separate converters for intramodule balancing bidirectional connection to a load and charging from an external power source are employed. this paper, integrated reconfigurable converter high-voltage storage systems is proposed. The main advantage of the proposed that it can be reconfigured operate in different operating modes: feeding system, backup source, regenerative mode, mode. Unlike conventional topology shares semiconductor devices...

In conventional parallel hybrid energy storage systems (HESSs), there are usually two cascaded converters active when transferring between its (ESSs) that result in the overall efficiency drop. Moreover, dc-link capacitor has to be oversized limit voltage ripple during simultaneous exchange ESSs and load feeding. The integrated reconfigurable configuration for HESSs proposed this paper allows direct transfer by using only a single converter bypassing dc link. This reduces stress on link,...

In the integrated reconfigurable converter (IRC) topology for high-voltage series-connected battery module systems, can be reconfigured into a range of operating modes: "feeding load" mode, "battery modules balancing" "regenerative" "charging" and "backup" mode. most applications, battery-balancing system operates while another is used as controllable power interface between load. However, during conventional IRC operation, modes cannot operated simultaneously. this paper, new balancing...

In conventional hybrid energy storage systems (HESSs), parallel bi-directional boost converters are used as interface between each system and the dc link. One of disadvantages configuration is that during transfer two active which in turn lowers overall efficiency. this paper, a new multiple converter topology for HESSs proposed. proposed one replaced with buck-boost by adding additional semiconductor switch can be reconfigured to bypass exchange interval. This improves Furthermore, allows...
