Danfoss has introduced the iC7-Hybrid, a 1500 VDC liquid-cooled grid converter aimed at energy applications that need more power in less space. Silicon carbide (SiC) technology and an advanced liquid-cooling system give it a very high power density and an efficiency of 99.2%, which helps lower operating costs over the life of the installation. Because grid-forming control is built in, the converter can maintain a stable supply in grid-connected and standalone systems alike, supporting the transition to renewable energy.
The iC7-Hybrid is intended for projects where compact size and efficiency come first. Its liquid-cooled design carries heat away from the electronics instead of releasing it into the surrounding air, which keeps performance consistent and improves reliability. A sturdy aluminum frame shields the sensitive components from vibration and harsh environmental conditions, so the converter suits demanding installations.
Danfoss builds the converter on more than two decades of experience with grid-forming technology. It switches smoothly between on-grid and off-grid operation while keeping the power supply stable. Its fast control loops and high control performance are designed for low-inertia networks, where conventional equipment often struggles.
Cybersecurity is another priority. The iC7-Hybrid is developed in line with the IEC 62443-4-2 standard, which protects the power conversion system against unauthorized access.
To make integration easier, Danfoss also offers a broad set of simulation models. Model-based design keeps them accurate and up to date. These digital twins of the converter allow detailed grid integration studies before installation, so the connection to your system can be verified in advance.
Overall, the iC7-Hybrid 1500 VDC liquid-cooled grid converter combines efficiency, security and intelligent control in one solution, and it is well placed to support a more sustainable energy landscape.
