High-Efficiency Power Converters for Marine Use
A bidirectional DC/AC converter that lets you connect a battery to an AC bus, charging and discharging the battery storage as required to improve energy efficiency and reduce emisions.
Abstract. This paper presents the design and simulation of a bi-directional battery charging and discharging converter capable of interacting with the grid.
Inverter: Similarly constructed with a MOSFET bridge, this unit serves as the bidirectional inverter, converting DC power back to AC power. The design of this bidirectional inverter circuit is critical for performance. Battery: Stores electrical energy.
AC/DC topologies Bi-directional converters use the same power stage to transfer power in either directions in a power system. Helps reduce peak demand tariff. Reduces load transients. V2G needs “Bi-Directional” Power Flow. Ability to change direction of power transfer quickly. High efficiency >97% (End to End) at power levels up to 22KW.
The effectiveness of the bidirectional power converters is verified by developing a 51-W charging prototype system, which improves the system efficiency by 3% in simulated seawater. It is essential for an autonomous underwater vehicle (AUV) to recharge at a nearest docking station (DS) when it runs out of its battery [ 1, 2 ].

The inverters enable ships to connect to smart grids, opening up opportunities for grid-to-ship power supply and bidirectional power flow. Ships with these inverters can return surplus power
Several countries promote supplying the vessels when they are docking at ports from renewable energy systems by establishing dedicated funding mechanisms to remove the obstacles
In normal HEV''s mobility mode, the battery and ICE, both power the electric motor while ICE uses gasoline fuel. The main drawback of HEVs is that the battery cannot be charged from an
This design allows for seamless connection of vehicles with varying voltage requirements through a single connector. In the initial stage, it operates as a rectifier during battery charging, seamlessly
At its core, bidirectional charging flips the typical path: instead of AC from the grid becoming DC for the battery, stored DC is inverted back to AC for a load or feeder. This conversion
