DC-DC Power Converter for Industrial, Smart Grid and E-mobile Applications

Siemens has introduced a second addition to its Sinamics DCP product family of scalable (4X), bi-directional DC-DC drives. The DCP 120 kW facilitates the integration of larger energy storage systems such as batteries and supercapacitors into multi-generator applications for a wide variety of industrial, smart grid and e-mobile uses, including photovoltaics, fuel cells, wind power and high dynamic uses such as peak shaving.

This new drive features combined buck/boost capability in a single device for optimized interconnection between DC sources and energy storage devices plus the DC link for both motor inverter and infeed/grid inverter. Available in a wide voltage range from 0-800V DC, this new inverter enables connection of energy storage systems to the DC link of an active line module. Bi-directional energy flow and scalable power are further features, along with a high efficiency up to 98.6% maximum energy yield can be fed back into a power grid, island or industrial grid.

The compact footprint of the DCP 120 kW converter results from the built-in reactors and control unit for space-saving design use. The built-in control unit also permits stand-alone operation of the drive. Profinet or Ethernet/IP are standard for Profibus communications.

Different infeed sources such as solar, fuel cell and wind power can be connected to realize a multi-generator power system, further broadening the application of this unit.

Uses for this new drive include peak shaving using stored energy on centrifuges, presses, elevators, stacker cranes, gantry cranes and industrial lift trucks, as well as battery test systems, test systems for photovoltaic power plants, smart grid uses including energy storage on wind and solar systems, fuel cells and numerous marine applications such as emissions reduction, offshore platform winch and crane operations and charging technology for e-boats with battery power. In the emerging e-mobility market, the unit is suited for fast-charge stations for e-cars, e-buses and hybrid systems that incorporate motors in combination with fuel cells or supercapacitors.

The Siemens SINAMICS DCP 120 kW DC-DC converter has myriad uses in industrial, smart grid, marine and e-mobile markets. The unit features buck/boost capability for interconnection of DC sources with energy storage devices.
