REGENERATIVE UNITS AND LOW HARMONIC INVERTERS

The optional Active Front End (AFE) regenerative units have also been developed for complete solutions with ecoVert® inverters. Combined with BREUER® inverters, these form a perfect pair to create test benches as well as systems connected in the DC link.

The portfolio is complemented by the so-called low harmonic inverters, which are designed with IGBT power semiconductors instead of a standard B6 diode rectifier bridge. In contrast to the AFE unit, however, the low harmonic inverter cannot feed back. The THDi (Total Harmonic Distortion) is < 5 %.
