Power Electronics Company was established in 1989. It employs selected,
creative and ambitious workers open-minded for new trends in power
Starting from DC-drives standard
solutions in a short time it worked out and implement frequency
converters AFC and MFC series (with one- and three-phase
frequency converters can compete with many products available on the
market in terms of functionality and reliability.
They were presented in 1999 at VIII International
Mielec-town Fair and awarded as "the most innovative product of the
Recently introduced new series of
MFC-710 frequency converters was honored by Prof. Robert Szewalski
Grand Prix at TECHNICON 2005 Fair of
Technology in Gdańsk
From the moment of its establishment company has been carrying on
research and development work, initially independently, then together
with Technical Universities from Gdańsk, Warsaw and Lviv. In
cooperation with the Institute of Control and Industrial Electronics
(Warsaw University of Technology) we designed vector control
frequency converter with high generated torque at low speed. Applied
DTC-SVM method (Direct Torque Control - Space Vector
provides good dynamic response of drive.
Many of our frequency converters have been installed in Russia, Belarus
and Ukraine. Based on our technical documentation frequency converters
are made by "Izhevsky Radiozawod" (Russia) and "Silekt" (Belarus).
In Poland our products work in many significant factories, mainly as
PZS-type units (complex control and power units with frequency
converters) or TZS-units (power and control units with DC-motor drive
