What does a DC/DC converter do?
To help improve performance by making better use of energy, energy storage is increasingly being introduced into systems to create hybrid solutions. Various storage methods are being used but, due to reductions in battery costs and increases in energy density, battery utilization is seen as being the fastest growing and more easily integrated storage medium available today. DC/DC converters can be used to connect to sources such as batteries, super capacitors, fuel cells and solar panels.
Energy support close to the consumption
Due to the wide input range of the source voltages, for example battery, the VACON® NXP DC/DC Converter application can be used to match source voltage to a common DC bus system. This method utilizes the stored energy to create the right DC bus voltage required to operate the machinery running on these hybrid systems.
VACON® NXP DC/DC Converter is well suited to containerized energy storage solutions. Scalable solutions mean you can easily balance the grid while growing your plant. The VACON® NXP DC/DC Converter application can be installed in both liquid- and air-cooled VACON® NXP drive modules.
Supply voltages and power range
Air cooled:
- 3 x 380-500 V...180-1100 kW with battery voltages from 100Vdc* to 800Vdc**
- 3 x 525-690 V...200-1200 kW with battery voltages from 100Vdc* to 1100Vdc**
Liquid cooled:
- 3 x 380-500 V...160-1800 kW with battery voltages from 100Vdc* to 800Vdc**
- 3 x 525-690 V...210-1800 kW with battery voltages from 100Vdc* to 1100Vdc**
*Minimum voltage is case dependent
**Depending on system DC bus voltage. Source (battery) voltage must always be lower than the DC bus voltage.
