Bi-Directional Battery Charger
 |
The Bi-Directional Battery Chargers were developed as standalone DC/DC modules that integrate directly with the 5kW Grid Connected 3 Phase Inverter Modules. The battery chargers are currently available in two options, 2.5kW (40-65VDC Battery Voltage) and 5kW (320-445VDC Battery Voltage). The battery chargers interface to a nominal 650V DC bus. The Converter enables charging or discharging of the Batteries through bi-directional power flow. The DC/DC Module is galvanically isolated. Its control power is independently supplied as the unit is primarily designed for laboratory microgrid testing. |
Custom solutions can be produced in both isolated and non-isolated configurations to suit your specifications.
Creative Power specializes in the development of custom solutions to meet specific customer requirements. This is achieved through Creative Power's extensive "building blocks" of controllers and power stage designs. Contact us if our listed products don't quite meet your requirements.
