AC ↔ DC · BIDIRECTIONAL
The bidirectional Power Module manages the charging and discharging of energy storage systems, offering advanced grid support functions in grid-following and grid-forming modes.
DC ↔ AC · HIGH-EFFICIENCY
High-efficiency DC/AC conversion for utility-scale systems, with DC voltages up to 1500 V and optimised management of trackers, strings and MPPT logic across two independent ports.
AC ↔ DC · CONTROLLED
Stable and precise power supply for electrolysers in Power-to-X applications, with continuous control of the DC current and integration into systems ranging from a few MW up to industrial scale.
CONNECTIVITY AND NETWORK QUALITY
Reliable conversion infrastructure for backup, integration with storage systems and peak load management, delivering the operational continuity required by mission-critical environments.
Overview
A converter designed in three levels.
UniQube is structured across three levels of progressive integration: the AD9000 Power Module as the technological core, the PCS as a complete conversion unit, and the Power Unit as an integrated system solution. Three tiers, a single scalable architecture.
Power Module
Innovative three-level converter featuring a flying capacitor topology and a modular design. Up to 2.5 MVA per module, already designed to accommodate market developments up to 2000 V.
Performance
Architecture built to last.
Every component of UniQube is designed to operate stably and continuously, even under the most varied conditions. From the cooling system to the Power Module and the transformer, every technical decision is made to ensure efficiency, long-term reliability and ease of management.

Greater efficiency, greater control,
greater safety.
Liquid-cooled converters.
The water-cooling system for the Power Modules allows for higher rated currents and ensures continuous performance even in hot climates. The glycol/water mixture extends the operating range down to -20°C as standard and -40°C for harsher environments.
Quick access to internal components
Flip-up panels with gas springs open up front access in a matter of seconds. Every component is accessible without dismantling load-bearing structures, reducing inspection and maintenance times in the field.
Optimal ergonomics and intuitive operation
The internal layout is designed so that every component – Power Module, filters, safety devices, controls – can be located immediately. A design choice tailored to maintenance personnel, not just designers.
Simplified maintenance of the converters
Quick-connect fittings for the hydraulic circuit
Single or dual DC interface configuration
The same platform for different markets
Maximum power
0 MVA
Available in a 5 MVA version with a single PCS in a 20’ container, and up to 10 MVA in a single power unit, with two PCS integrated into a 30’ skid.
Medium voltage
0kV
Medium-Voltage Ring Main Unit (RMU) compatible with the entire market range, SF6-free up to 24 kV.
