High-power bidirectional energy storage inverter

What is a bi-directional Converter?

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.

How can energy storage technology improve the power grid?

The energy storage technology can be used to suppress the output fluctuations of wind and solar energy, and to improve the power grid capability of absorbing the new energy. Resultantly, the utilization of renewable energies is increased , , and the stability of the grid is improved.

What is a bidirectional power directing switch?

Bidirectional Power Directing Switches The purpose of the two switches is to channel the flow of power from the panel or to the load depending on the state of the system. When the system is in the battery charging state, MOSFET Q3A is turned on and MOSFET Q3B is turned off. Power flow occurs from the panel to the battery.

Which energy storage unit has the highest energy density?

The key storage units have great impact on the system cost and size, and mainly include superconducting energy storage , flywheel energy storage and electrochemical energy storage, etc. , . Among them, electrochemical energy storage, such as lithium batteries, has the highest energy density.
