The necessity to reduce the risks in environmental pollution has paved way for options that help minimizing it. Electric vehicle is one such option and most evolving means this field. EV system order achieve a high peak requires multiple sources be integration. So, bidirectional buck boost DC converter with four port realized research integration of many instead using dedicated converter. This ...

A foundational property of bidirectional transformations is that they should be correct: that is, the transformation should succeed in restoring consistency between any models it is given. In practice, however, transformation engines sometimes fail to restore consistency, e.g. because there is no consistent model to return, or because the tool is unable to select a best model to return from amo...

The Vienna rectifier can produce three voltage levels, however only the connection to neutral-point is fully controllable using bidirectional switches. When not imposed in a phase-leg, polarity of pulses generated depends on diode that conducting which defined by current direction. As result, go opposite direction what demanded controller, and becomes distorted. This be mitigated injecting part...

Battery energy storage systems (BESSs) can control the power balance in DC microgrids through injection or absorption. A BESS uses a bidirectional DC–DC converter to flow to/from grid. On other hand, any fault occurrence switches of may disturb and stability microgrid and, thus, safe operation battery bank. This paper presents fault-tolerant topology along with diagnosis algorithm for BESS. The...

This paper presents a single-objective model predictive control for bidirectional DC-DC flying capacitor (FC) converter, which integrates battery to the microgrid. The presence of multiple FCs facilitates converter interface low-voltage high-voltage DC bus at reduced voltage stress on its power switches. However, such requires controller that fulfils objectives, namely and FC regulations, flow....

This paper proposes a high efficiency and conversion ratio bidirectional isolated DC-DC converter with three-winding coupled inductor, which can fulfil storage system charging discharging. The proposed topology is improved from traditional Buck-Boost converter. By integrating inductor switched-capacitor into power stage, the achieve merits of isolation flow. has only four switches common core g...

Depending on whether bidirectional links or unidirectional links are used for communications, the network topology under a given range assignment is either an undirected graph referred to as the bidirectional topology, or a directed graph referred to as the unidirectional topology. The Min-Power Bidirectional (resp., Unidirectional) k-Node Connectivity problem seeks a range assignment of minimu...
