Using a high-power (1.5MW) converter design and silicon carbide (SiC) semiconductor switches, enabled by PPS’ patented AC-link circuit topology, will allow for a much higher power-density and allow direct connection to 12 kV or higher power lines without a transformer, says the company. This will drastically reduce the space and logistics requirements for the power electronics in tidal, wave, and other hydropower systems, and increase the efficiency of transmitting power and interconnecting with the utility grid, said PPS.

“We are excited to expand the use of our technologies to the rapidly growing sector of grid-connected hydropower applications,” commented Darren Hammell, Executive Vice President of Business Development. “Our history of providing rugged components for Navy applications will ensure that our designs can endure the unique environmental requirements of these systems.”
