HVDC transmission system architectures and use cases
High-voltage dc power transmission (HVDC) use is growing across a variety of applications. One of the main growth drivers is renewable energy. HVDC interconnects between geographically dispersed wind and/or solar farms can help mitigate the effects of variable energy generation levels by providing a means for averaging the various changing power outputs. HVDC is already […]

Simulation software boosts productivity for early power component designs
Synopsys, Inc. announced the industry’s most comprehensive virtual prototyping solution to accelerate power electronics system design from concept to validation for power components to large complex systems. As part of the solution, Synopsys introduced SaberEXP to deliver fast simulation convergence and higher productivity for early power component design, such as power converter and motor drive. SaberEXP also provides […]
HVDC converters, components, and control systems
While the use of high-voltage DC (HVDC) results in lower transmission losses compared with high-voltage AC (HVAC), 5-6% losses for HVDC versus 8-10% for HVAC, the overall cost-justification for HVDC is more complicated. HVAC terminals are much less expensive than the power electronics-intensive HVDC terminals. But HVDC cabling can be less costly than an HVAC […]
Over a century of high voltage DC power transmission
Even though ac power transmission dominates as a result of its flexibility in delivering power to end users, dc power transmission has been used to send higher power levels over longer distances for over a century. The earliest high-voltage DC (HVDC) power transmission systems, starting in the 1890s and continuing through the 1930s, used the […]
