Ultracapacitor solution balances gradients and smooths genset power.

Benefits of the Skeleton solution

  • VSG can achieve immediate response<20 msec on load variations with high gradients
  • Engine can run at the most beneficial operating speed
  • Increasedengine life through less wear and tear
  • Uninterruptible power supplyin case engine is off


High degree of random load variations


  • Random high load variationscan cause problems for Variable Speed
  • Generators to continuouslysupply power with high gradients

Key challenges

  • High degreeof random load variations
  • Maintaining stabilityof power generation
  • Operating efficientlyand improving fuel economy
  • Longerrestart time

Known consequences

  • Generator power gradients outside the limits
  • VSG is not able to meet the load demand
  • Shorterlifetime of engine



UCAP balance gradients and smooths genset power

What we offer

  • Ultracapacitor solutionconnected to the DC link of power conversion system
  • Ultracapacitors deliver necessary powerto compensate the load variations and smooth out genset power
  • Ultracapacitors are the only viable technologyto provide high power and high duty cycle
