Variable Frequency Power Supply
Since vessels may need both 50Hz and 60Hz electricity, whereas local grid may not be able to supply, frequency conversion is necessary.
The AC-DC converters are the core of power supply. Besides, other auxiliary equipments, such as transformer and circuit breaker cabinet, are necessary.
There are two types of variable frequency power supplies in the PCS-9569 shore power system:
Low-voltage PCS-9569L
Max. 1MVA ;
Modular design and structure topology in parallel ;
Three-phase controllable AC-DC converter for each module.
High-voltage PCS-9569H
2~20MVA ;
Modular design and structure topology in serial.
