Description
The active REVCON Harmonic Filter – RHF-Active is a high efficient active harmonic filter used to avoid mains distortion caused by any non-linear loads such as variable frequency drives. Revcon offers 3-level IGBT based filter, but also a unique Silicon Carbide (SiC) based Active Filter!
Ideally, all loads and sources have a pure sinusoidal current waveform. But unfortunately the true waveform of most equipment is very different. Nonlinear loads as for example the diode input bridge of a 6-pulse drive are causing a distortion of the mains voltage. This distortion typically evaluated by the Total Harmonic Distortion THD, evaluates frequencies from the second up to the 50th harmonic. In a 50Hz Network this is the area between 100Hz and 2,5kHz.
The impact of the voltage distortion is diverse, and the most typical effect is overheat of transformer and PFC applications (Capacitor banks). An underestimated impact of harmonic distortion is the significantly reduced lifetime expectation of electrical and mechanical equipment.
The active Revcon Harmonic Filter reduces the THDi of nonlinear loads and sources to typically below 5% (fully scalable). This is necessary to reach various standards and recommendations, such as IEEE 519-2014. Due to the high switching frequency of the RHF-Active, the compensation of high order harmonics is very efficient and accurate. Due to its unique circuit, the RHF-Active is extremely efficient which allows for a very compact design.
All RHF-Active can be used as 3P4W or 3P3W for 380-415V systems (further voltage levels coming soon!). Unlimited current possibilities due to open end in parallel setup! Looking forward to meet you at our Stand!
