Techno Power Systems

We are offering Third Harmonic Filter to our clients.

The Third Harmonic Filter Panels is connected in parallel with the AC line, and constantly injects currents that precisely correspond to the harmonic components drawn by the load. The result is that the current supplied by the power source remains sinusoidal.

The idea of Thahird Harmonic Filter Panels is relatively old, however the lack of effective techniques at a competitive slowed its development for a number of years. Today, the wide-spread use of IGBT components and the availability of new digital signal processing (DSP) components are paving the way to a much brighter future for the Active Harmonic Filter.

The Third Harmonic Filter Panel concept uses power electronics to introduce current components, which cancel the harmonic components of the non-linear loads. A number of different topologies are being proposed and are discussed below. Within each topologies there are issues of required components ratings and method of rating the overall filter for the loads to be compensated.
