DCP DC/DC converter power spectrum extended to 120 kilowatts

• Minimal space requirement due to high switching frequency
• Voltage range up to 920 volts
• UL certification opens up application for American market

Siemens has extended the power range of its Sinamics DCP DC/DC power converter from 30 to 120 kilowatts. The high switching frequency allows the use of smaller chokes, making the Sinamics DCP extremely economical on space.

It covers a voltage range of up to 920 volts DC, and by offering facility for 4x parallel switching it makes available a total output of up to 480 kilowatts. With its UL certification, it also meets the conditions for use in the American market, and compliance with the Drives and Photovoltaic Standard opens up further interesting application scope in these fields for the Sinamics DCP.

The Sinamics DCP DC/DC power converter enables the realization of energy storage systems using for instance batteries or supercaps, offering a range of benefits for the user: As a combined buck/boost converter, the Sinamics DCP can be adapted to the relevant voltage at the input/output, ensuring optimum charging of either a battery or supercap, as well as making available the stored energy to a DC link.

As the control and operating units are also integrated in the device, the DCP is capable of fully independent operation. An overload capacity of up to 150 percent of rated current allows the Sinamics DCP to also be used in the implementation of highly dynamic applications. A Profinet interface is also available for integration into industrial networks.

The Sinamics DCP can be used in applications such as energy storage systems in photovoltaic installations or wind power farms, alongside press applications, diesel-powered harbor cranes, rack handling systems or quick-charging stations for eCars. The Sinamics DCP has already been successfully installed at the Karlsruhe Institute of Technology (KIT) in a hybrid system comprising a battery with 50 kWh and a PV field.

The energy generated is stored partially in the battery or fed into the grid at peak load periods. In another installation near Augsburg, energy generated by a photovoltaic system is stored via Sinamics DCP in a battery. This is used in the event of a power failure, providing the guarantee of practically uninterrupted continued operation of the plant.
