Energy storage DC/DC Converter

Bidirectional DC/DC converters have been widely used in fields of electric vehicles, industrial control, battery R&D, etc. due to their unique advantages. In an actual energy storage system, a topology consisting of multiple DC/DC converters and a grid-connected bidirectional PWM converter is usually used. The voltage of the connection point between DC/DC converters and the grid-connected bidirectional PWM converter is called DC bus voltage. When the battery is charging/discharging, the DC/DC converter can feed back/absorb energy to/from the DC bus according to the system requirement. The grid-connected bidirectional PWM converter ensures the stability of the DC bus voltage through the bidirectional energy flow with the grid.

 

Product Naming

For example: the model of Titans 60KW non-isolated energy storage DC/DC module with a DC bus voltage of 750V is TDC-F60/750N-A.
