High Frequency Isolated PCS Power Module 200kW 750V Bidirectional Energy Storage Converter

200kW  750V Bidirectional High Frequency Isolated PCS Power Module energy storage converter system

[Product Description]

V2G, or Vehicle to Grid, is a concept that aims to achieve bidirectional interaction between electric vehicles (EVs) and the power grid. It utilizes the energy storage of EVs as a supplement to the grid and renewable energy sources. By taking advantage of peak/off-peak price differentials, it enables charging during off-peak periods and grid discharge during peak periods. It is also known as AC/DC bidirectional power module.
The AC/DC power supply adopts three-level technology to achieve bidirectional conversion between AC and DC. The DC/DC converter utilizes high-frequency isolated bidirectional conversion technology, specifically soft-switching resonant technology, which offers high efficiency and automatic switching between charging and discharging. The product is designed with dual DSP to ensure stable bidirectional performance of AC/DC and DC/DC modules. It supports module parallel connection, as well as CAN and RS485 communication for easy communication and control with third-party devices.

This power supply is widely used in various fields, including energy storage, battery pack integration, emergency power supply, disaster relief power supply, and equipment aging. It is the preferred product for industries that require bidirectional energy flow.
