SIMON Supra Harmonic Filter
SIMON One of its kind Voltage-Controlled Active Filter based on next generation Silicon-Carbide Technology is designed to filter supra harmonics and complex resonances together.
SIMON Supra Harmonic Filter
SIMON® Voltage-Controlled Active Harmonic Filter
SIMON is one of the latest innovations from Condensator Dominit which is based on next generation semiconductors Silicon Carbide (SiC) technology. Unlike conventional Active Harmonic Filters (AHF) which filters harmonic based on current sensing, SIMON is an active filter which is based on voltage-control method. This eliminates the need for complex installation of current transformers. This means that production processes are not affected during installation and maintenance work.
Due to SiC Technology, SIMON sets new standards in achieving efficiency for active harmonic filtering. SIMON, developed with patented control algorithms, is the only active filter in the world offers following unique additional advantages:
⦁ Filtering of supra harmonics
⦁ Resonance damping
⦁ Extremely efficient and highly dynamic reactive power compensation
SIMON is a perfect tool in our PQ Toolbox in eliminating higher-order harmonic distortions with extremely low-losses. Along with harmonic filtering, it offer unique feature for damping resonances or oscillation in the mains. This can be, for example, a network resonance that cannot be eliminated with an ordinary LC-circuit. The resonance point is merely shifted to a higher frequency with such a filter. Even conventional, current-controlled active filters cannot effectively counteract resonance-induced voltage levels. SIMON voltage-controlled active filters, on the other hand, damps the network resonance and behaves as a high-pass filter.
This patented control method introduces damping into the power system and can thus eliminate resonances and reduce voltage levels over a wide frequency range. Compared to a real resistor, SIMON® does not convert the absorbed active power into dissipated power – i.e., heat. Instead, it is extracted from the harmonics and fed back into the network node in the form of fundamental active power. The patented control method thus effects a local energy recycling directly at the connection point.
