POWER DRIVESWärtsilä active front end rectifierThe Wärtsilä Power Drive can also be delivered with an active rectifierfront end which allows for energy flow in both directions, eliminatingthe need for transformers and braking resistors. Direct Current Controland a network filter give small ripple currents and very low harmonicdistortion well below international standards.Wärtsilä passive rectifierThe Wärtsilä Power Drive can be delivered with a diode rectifier in a 12,18 or 24 pulse configuration, very well suited to either a Wärtsilä LLCsystem or a standard transformer solution.Wärtsilä Multidrive systems, DC sourcesThe Wärtsilä Power Drive can also be delivered as a multidrive system,where the inverters are connected to the same DC-link. Combined withour patented electronic DC breakers, these work independently. Themultidrive system can be connected to the main grid through eitheractive or diode rectifiers, and can also allow for DC-sources such asbatteries and fuel cells.ModelPowerMWIn maxmotor (1)Current(A)Wärtsilä passiverectifier driveWidth(mm)Weight(kg)Wärtsilä activefront end rectifier driveWidth(mm)Weight(kg)0.8 800 900 800 900 1 6001.5 1 500 900 900 1 500 2 2002.7 2 700 1 500 1 400 3 000 4 6003.8 3 800 2 100 1 900 5 100 7 7005.5 5 500 2 700 2 300 6 600 9 7001) In max motor is the highest possible nominal current we can give to the electric motor from the drive.All cabinets have 1 000 mm depth and 2 051 mm height.33
