Power Converters for modern energy systems - Introducing DEIF iE Convert

Modern energy and power systems demand high‑efficiency, compact, and flexible power converters capable of integrating diverse energy sources across land and sea. The iE Convert power converter range from DEIF delivers exactly that: cutting‑edge silicon carbide (SiC) technology, modular scalability up to multi‑megawatt levels, and exceptional efficiency for hybrid AC/DC systems.

High‑Efficiency power conversion with silicon carbide technology

DEIF’s iE Convert devices are built in partnership with AVL and Wolfspeed, utilizing silicon carbide MOSFETs to achieve very high switching frequencies, minimal power loss, and near‑flat efficiency curves across all load factors. This results in reduced cooling demand, higher thermal performance, and consistent energy savings in demanding applications on land and at sea.

The high switching frequencies-reaching up to 100 kHz-enable smaller filters, lower harmonic distortion, and more accurate energy transformation, producing clean, high‑quality output power.

Compact, lightweight, and built for demanding environments

One of the biggest advantages of the iE Convert power converter is its compact modular design. Compared to traditional IGBT‑based converters, iE Convert devices can reduce installation space by up to 60% and cut weight by up to five times - a significant benefit for marine engine rooms, mobile power units, and Battery Energy Storage Systems (BESS).

The marine variants also offer 30-40% weight reduction and maintain extremely high efficiency (up to 99%), contributing to lifetime fuel savings and lower cooling requirements.

Flexible, scalable power conversion for any scenario

The iE Convert platform supports a wide range of applications with its bi‑directional modules. Each unit can operate as a converter, inverter, rectifier, transformer, or variable‑speed drive, making it adaptable to:

• Battery charging/discharging
• Fuel cell integration
• Propulsion systems
• Hotel loads and deck equipment
• PV and renewable energy integration
• Industrial drives and smart grid applications

With capacity options ranging from 125 kVA to 6 MVA and the ability to parallel up to eight power blocks on a single controller, iE Convert enables engineers to build fully customized energy solutions, from small systems to multi‑megawatt installations.

Built‑in filters, galvanic isolation, and safety features

Every iE Convert unit comes with:

• Built‑in filters
• Galvanic isolation (critical for fuel cell and hybrid systems)
• Liquid cooling
• Comprehensive voltage, current, and fault monitoring

These features eliminate the need for additional filtering hardware in most installations and ensure safe operation in complex hybrid energy environments.

A complete control solution from one supplier

DEIF further strengthens the value of iE Convert by offering a complete control ecosystem, including cybersecure controllers, meters, and PLC integration through CODESYS. This single‑supplier approach streamlines procurement, integration, and long‑term support, backed by decades of experience in power and energy management.

Whether for marine propulsion, hybrid grids, industrial applications, or renewable energy storage, the iE Convert power converter range delivers unmatched efficiency, scalability, and technical performance. With its SiC‑based innovation, modular architecture, and built‑in safety features, iE Convert stands out as one of the most advanced and versatile power converter solutions available today.
