WELCOME TO ODCA

When the Grid Holds You Back,
Direct Current Moves You Forward.

The electricity landscape is already DC almost everywhere, but we use AC to connect loads, sources, and distribution with each other. This needs many conversion steps, is inefficient, and needs more invest and installation effort.

ODCA helps you with the transition.

Direct current grids have long been part of real-world applications. Today, they are used in industrial environments, in buildings, as well as in charging and IT-related infrastructures. At the same time, many companies are still at an early stage when it comes to a systematic understanding and planning of DC-based architectures.

HOW DC GRIDS

Understanding direct current grids:
from planning to implementation

Modern power electronics, new protection concepts, and simulation methods have now created the prerequisites for implementing DC grids in a realistic and robust way.

Anyone planning a DC grid must ask different questions than in the AC environment: Which voltage levels are suitable for the application? How do we design protection and selectivity? How do we integrate storage systems and generators? These questions are demanding. But they are solvable: with clear fundamentals, proven practical references, and the right partners.
