The PQFA monitors the line current in real time and processes the measured harmonics as digital signals in a high-power DSP (Digital Signal Processor). The output of the DSP controls PWM (Pulse Width Modulated) power modules that through line reactors inject harmonic currents with exactly the opposite phase to those that are to be fi ltered.
3. PQFA principle and characteristics 3.1. Reasons for limiting harmonics the harmonic pollution in electric networks. Examples of such equipment include drives during a fraction of the fundamental period. This is how such equipment can obtain their main properties regarding energy saving, d

The PQFA active filter is used to solve the harmonic problems in this induction heating application. Some key points: - The PQFA filters harmonics from the drives and induction heating loads, reducing harmonic distortion. - It compensates for the reactive power demand of the harmonic loads, reducing the loading on the detuned capacitor banks. - By filtering harmonics and compensating reactive ...
These conditions, when excessive, lead to frequent equipment failures or reduced lifetime of the equipment, production losses, reduced safety levels of installa-tions, increased carbon footprint, non-compliance with utility regulations and other undesired effects. In addition to finan cial losses there are costs incurred due to extra kWh losses in typical net-work components such as ...
