Hsu, AC Power Corp.: "There are more
and more requirements on the larger size
of regenerative power supplies. For solar industry, they may need a 1MVA grid
simulator. For the wind turbine industry,
they may need larger than a 2MVA grid
simulator. For most of the testing power
supply manufacturers, they may have to
parallel connect multiple power supplies
to achieve this high kVA requirement.
But the reliability and MTBF (mean
time between failure) will decrease at
the same time."
footprint in the lab as well as minimizes
the cost. Chroma has responded to our
customers by developing a series of regenerative electronic loads and bidirectional
power supplies."
Weiss, NH Research: "Customers are
demanding modular configurations,
expandable power, integrated safety
features, wider operating envelopes,
built-in measurements, and faster transient response times for the testing of
today and tomorrow's products. There
is a general trend by all modern suppliers to use SiC and GAN-based switches.
These devices permit higher switching
frequency and therefore higher power
densities."
van Eijkelenburg, PPST Solutions:
"Increasing power demands are pushing
up the size of regenerative power products
to ever higher power levels. This applies to
AC sources, DC supplies, and electronic
loads alike. As power levels increase, energy savings resulting from using regenerative products can result in significant
cost savings for customers on both utility
bills and HVAC bills."
Infineon Technologies' PrimePACK3+ 1700 V,
1800 A dual IGBT module.
Dr. Nagarajan, Infineon: "The key challenge faced by wind energy in general and
wind turbines in particular is optimizing
the total cost of ownership. Wind farm
operators have to calculate the payback
period for their investments. For this reason, reliability and energy efficiency are
becoming increasingly important."
What are customers asking for?
What features or innovations are customers asking for in regenerative power
supplies & sources?
Drodt, Chroma: "Mostly, our customers
ask for versatility in the supply's functionality; meaning the same unit could be applied as regenerative source or a regenerative load. This versatility reduces the
