Bi-Directional DC Converter

Key characteristics of ARDA’s patented non-isolated Bi-Directional DC Converter include:

• Based on bi-polar grounded battery banks
• Modular and scalable from low power to high power
• Enables independent management of battery banks
• Limits short circuit energy of ground faults without relying on fuses/breakers
• Reduces cost and simplifies control

Key benefits of ARDA’s non-isolated Bi-Directional DC Converter for distributed energy applications integrating storage include:

• Lower and safer voltages with respect to ground simplifying monitoring and reducing cost
• Reduced short circuit energy in faults to ground
• Easy integration with renewable sources
• Easily adaptable to different battery technologies
• Improved battery lifetime by enabling independent management of smaller battery banks
• Increased system availability

Key benefits of ARDA’s non-isolated Bi-Directional DC Converter for stand-alone energy storage applications include:

• Simple and low cost topology that allows the use of bipolar batteries reducing potentials to ground for safer operation and simpler battery management instrumentation
• Increased safety by limiting battery current contribution into DC link short circuits to low currents of very short duration without the activation of fuses or breakers
• Easy detection of battery internal faults to ground without the need for complex fusing schemes or instrumentation
