Description of product configuration

Converter technology

Forming and controlling circuits, composing complex power electronics and systems.The so-called "conversion" means that the alternating current becomes direct current, the direct current changes to alternating current, the direct current changes to direct current.


Power quality

Refers to the quality of electrical energy in the power system. The ideal electrical energy should be a perfectly symmetrical sine wave. Some factors cause the waveform to deviate from the symmetrical sine, which creates a power quality problem. Power quality problems can be defined as: voltage, current, or frequency deviations that cause a powered device to fail or not function properly. In modern power systems, voltage sag, temporary rise and short-term interruption, and harmonic distortion of voltage waveforms have become the most important power quality problem.

The frequency converter is one of the most commonly used components of AC motor control equipment. At present, inverters can be found in all industrial fields as well as in the field of home automation. In view of the demand for ultra-small,  high-efficiency  energy conversion equipment, inverter manufacturers use IGBT switching and PWM technology. This can cause many problems for OEMs and system integrators, from functional degradation to very severe motor damage. Saton reactors and filters reduce the  harmonics in  the line and the effect of the drive output on the motor.
