20kW 750V Bidirectional High Frequency Isolated DCDC Power Module
[Product Description]
The DC/DC module adopts high-frequency isolated bidirectional
conversion technology, specifically soft-switching resonant
technology, which provides high efficiency and enables
bidirectional energy flow with automatic conversion between
charging and discharging. It is designed with DSP and supports
module parallel connection, as well as CAN/RS485 communication for
easy communication and control with third-party devices.
This power supply module is widely used in applications with a
common DC bus, such as photovoltaic energy storage, energy storage
with charging and discharging, battery utilization, and
vehicle-to-grid (V2G) scenarios. With high-frequency isolation
between the battery and the DC bus, it is the preferred product for
industries that require bidirectional energy flow.

[Application Fields]
Applications of "PV energy storage and charging" or "energy storage
and charging" in complementary multiple energy scenarios:
In scenarios such as large-scale charging stations or battery
swapping stations, integrated "photovoltaic energy storage and
charging" or "energy storage and charging" stations utilize clean
energy sources. The generated solar energy is stored in the energy
storage system, forming a microgrid that integrates photovoltaics,
energy storage, and charging facilities. This microgrid can
intelligently interact with the grid according to demand, enabling
both grid-connected and off-grid operation modes. The use of energy
storage systems can also mitigate the impact on the regional power
grid during high-current charging of electric vehicles.
Additionally, it can help with peak shaving and valley filling,
taking advantage of price differences in electricity tariffs.
By adopting a shared DC bus power supply scheme, including
photovoltaics, energy storage, charging stations, DC/DC loads,
etc., the number of AC/DC conversion stages is reduced, resulting
in lower investment costs and improved system efficiency.
Vehicle-to-Grid (V2G) technology, which utilizes bidirectional DC
charging stations, allows electric vehicles to not only charge but
also discharge, enabling controlled two-way interaction and energy
exchange between electric vehicles and the grid. This enables
electric vehicle owners to charge their vehicles with cheaper or
off-peak electricity and discharge during peak hours to earn the
price difference. V2G also enhances load flexibility, reduces
distribution network investments, facilitates the integration of
clean energy sources, and promotes the development of the electric
vehicle industry while reducing the footprint of public charging
facilities.
