6-1. Automatic Battery CV Mode

Battery voltage is maintained at set target voltage. If battery voltage is lower than the target voltage : Generation Operation BChargeC If battery voltage is higher than the target voltage : Regeneration Operation (Discharge)

Constant current control is for batteryside current both generation operationand regeneration operation. Battery bus rump up mode can be selectedfor charged up capacitor of battery side from 0V and/or for operation as bus converter.

By apply external voltage,HVDCside is more than 250VDCorLVDC side is more than 28VDC the control circuit will be initialized and setting information will be loaded from the non-volatile memory. At this point each LED will light up and turn off after completing the initialization process. If the internal interface detects abnormality for some reason, the LED will remain lit up. After the initialize process, theconverter will bein waitingmode. Power conversion operation will start when the operation command is sent. The internal FANs are rotatedduring any power conversion operation. FANs will stop after approximately 3 minutes when operationis stoppedbyoperation command.

With this converter selection of operation mode such as Automatic Battery CV Mode, Automatic GridCV Mode or Manual CV Mode is possible. Note that power conversiondirection from HVDC (Grid)to LVDC (Battery) will be described as Generation Operation (Charge) and powerconversion direction from LVDC (Battery) to HVDC (Grid) will bedescribed as Regeneration Operation (Discharge).
