coolcept

Inverter topology providing top efficiency

What is coolcept?

Coolcept is an inverter topology developed by Steca that achieves the best efficiency among all inverters. The idea combines switching simplicity with maximum efficiency.

How does coolcept work?

The design uses symmetric step-down converters with downstream pole-reversing circuits. The separation into two different voltage levels allows the use of proven standard components.

The advantages of coolcept:

coolcept is cool
Clever switching design ... Use of proven standard components Reliability

coolcept is cold
Highest efficiency ... less heat dissipation

coolcept is efficient
Highest efficiency ... maximum yields

coolcept is long-living
Less heat dissipation ... longer service life

Inverters with coolcept:

The peak efficiency of this world record device is 99.1 %. Based on EU benchmarks, the device achieved an average efficiency of 98.7 % over the entire power range. The series devices achieve peak efficiencies of up to 98.6 %. This means that coolcept inverters are the most efficient single-phase inverters available on the world market.
