Development of a switched-capacitor DC-DC converter with bidirectional power flow
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 2000This brief presents a switched-capacitor dc-dc converter that offers features of voltage step-down, voltage step-up, and bidirectional power flow. Concept of energy transfer is achieved by using two current-controlled bidirectional converter cells, which operate in antiphase.

Stability analysis of cascaded converters for bidirectional power flow applications
INTELEC 2008 - 2008 IEEE 30th International Telecommunications Energy Conference, 2008This paper establishes the criteria to ensure stable operation of two-stage, bidirectional, isolated AC-DC converters. The bi-directional converter is analyzed in the context of a building block module (BBM) that enables a fully modular architecture for universal power flow conversion applications (AC-DC, DC-AC and DC-DC).

An Improved Triple Interline DC Power Flow Controller for Bidirectional Power Control
2020 IEEE REGION 10 CONFERENCE (TENCON), 2020For the operational safety and stability of electrical system, effective power flow control in meshed high voltage direct current (HVDC) grids makes sense. In order to realize the objective of controlling several lines simultaneously and independently in a convenient way, interline dc power flow controller (IDCPFC) has been introduced.

Bidirectional power flow control of a power converter using passive Hamiltonian techniques
International Journal of Circuit Theory and Applications, 2007AbstractA controller able to achieve bidirectional power flow for a boost‐like full‐bridge rectifier is presented. It is shown that no single output yields a stable zero dynamics for power flowing both ways. The controller is computed using port Hamiltonian passivity techniques for a suitable generalized state space averaging truncation of the system ...

Dc-Dc Bidirectional Cascaded Converter for Hvdc Network Using Bidirectional Power Flow Controller
2022In a Multi-Terminal High Voltage Direct Current (MTDC) system, Interline DC Power Flow Controller (IDCPFC) plays an important role in balancing the dc power flow in the transmission lines. However, the conventional dc power flow control methods have output voltage limitations and reliability concerns. Therefore, this paper proposes an interleaved dc-dc

A bidirectional power flow controller for EVs to support the grid
2015 50th International Universities Power Engineering Conference (UPEC), 2015The spreading of electrical vehicles leads to a positive impact on the mobility field from the ecological, economical and efficiency point of view. Unfortunately this diffusion is also potentially capable of negative reverberations on distribution and transmission networks, since EVs can be considered as a new load category. Rather than preventing this

A novel square-wave converter with bidirectional power flow
Proceedings of the IEEE 1999 International Conference on Power Electronics and Drive Systems. PEDS'99 (Cat. No.99TH8475), 1999A novel ZVS phase-shift controlled bidirectional DC-DC convertor is proposed. It possesses the conventional features of phase-shifted convertors, including constant switching frequency, zero-voltage switching (ZVS) and voltage control by phase-shift. However, the new convertor has been improved by developing a bi-directional power flow capability and ...
