Integrate energy storage into your drive system and make regenerative energy available where it is needed.
The SINAMICS portfolio offers two different approaches: the compact SINAMICS DCP combines all converter components in one device, while the modular SINAMICS S120 DC-DC Converter can be adapted to specific applications and integrated into an existing SINAMICS S120 drive lineup.
Why SINAMICS DC-DC converters?
Key benefits
Store and reuse regenerative energy
Temporarily store regenerative energy and make it available during the process, at peak loads or as backup during a power failure.
Integrate storage into your drive system
Connect batteries or ultracaps to the DC link and use existing SINAMICS tools and communication interfaces.
Choose the right converter architecture
Select the compact SINAMICS DCP for an integrated solution or the modular SINAMICS S120 DC-DC Converter for application-specific configurations.

SINAMICS S120 DC-DC Converter
Based on a SINAMICS S120 Motor Module and supplementary components, the SINAMICS S120 DC-DC Converter can be configured for specific applications. It integrates mechanically, electrically and digitally into the SINAMICS S120 drive lineup.
Best suited for:
- Existing SINAMICS S120 systems
- Application-specific configurations
- Modular drive architectures
- Integration with existing communication interfaces
- Complex industrial energy-storage applications
SINAMICS DCP
SINAMICS DCP combines all DC-DC converter components in one compact device. Its buck-and-boost functionality enables energy exchange between DC systems with different voltage levels, while parallel connection allows the power range to be extended.
Best suited for:
- Compact installations
- Limited control cabinet space
- Battery and ultracap integration
- Test stand applications
- Fast implementation with limited engineering
