Structure and Hierarchical Control Method of Battery‐Based Hybrid Power Flow Controller
International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.This article proposes a battery‐based hybrid power flow controller (B‐HPFC), offering enhanced flexibility for power flow regulation and energy storage. First, the structure of B‐HPFC is given, where the cascaded H‐Bridge (CHB) is integrated with the phase‐shifting transformer (PST). The batteries are connected to the modules of CHB.

Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.In this paper, a new method for multistage digital sigma–delta modulators (DDSMs) is presented to increase the output sequence period and reduce fractional spurs. The output of a DDSM is always a periodic signal when the input is constant. A hybrid DDSM is premiere to its conventional counterpart for having a potential speed, by the choice of its ...
