ACDC Cube

Summary

The need to integrate renewable energy sources and heavy loads such as electric vehicles in the low voltage grid is demanding for more light, flexible and reliable solutions.

Rewarded with the Semikron Young Engineer Award 2018, 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 network 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 standard solutions such as the voltage source converter plus dual active bridge. Due to its innovative features, ACDC Cube is especially suitable to applications where power systems dimensions have very tight limits.

Advantages

• COMPACT - with reduced weight and volume achieved through a new hardware solution;

• IMPROVED POWER QUALITY IN THE ELECTRIC GRID INTERCONNECTION - due to the use of a new control approach;

• INCREASED DURABILITY and RELIABILITY - by using less capacitors;

• SAFETY - provided by galvanic isolation.

Market Applications

• Vehicle-to-grid (V2G), vehicle-to-home (V2H) and vehicle-to-load (V2L);

• Aeronautical and aerospace applications;

• Energy storage systems;

• Solar inverter with integrated energy storage;

• Community energy storage.
