The Electrical Accumulator Unit (EAU) is a bi-directional DC-DC converter designed to work with a Li-Ion battery. It stabilizes a DC Bus during transients caused by electro-mechanical and regenerative loads, supporting peak power load demands to enhance generator mission capability. It captures regenerative voltage spikes and surges, returning them to a battery or ultra-cap power source, thus eliminating the need for dissipative solutions.
