Summary of the technology
ACDC Cube is a single-stage, bidirectional and high-frequency isolated power conversion system. ACDC Cube also uses a novel control method to do the interface between the Alternate Current (AC) distribution networks and a battery pack, or other Direct Current (DC) sources/loads, delivering higher power quality in a compact design.
ACDC Cube has lower total volume and weight, increased durability and equivalent reliability when compared with a standard solution such as the voltage source converter plus dual active bridge. Due to its innovative features, ACDC Cube is especially suitable for applications where the size of the power conversion system is critical.

The need to integrate renewable energy sources and heavy loads such as electric vehicles in the low voltage grid is demanding for more flexible and reliable solutions, such as community energy storage or vehicle-to-grid (V2G). Moreover, conventional power conversion systems are bulky and heavy.
INESC TEC engineers have developed the ACDC Cube technology to offer new options for micro-generation systems, including bidirectional conversion of electrical energy between home batteries or electric vehicles (DC) and the public electric grid (AC), or any other devices where dimensions restrictions are critical.
