Most of the mentioned filtering techniques have common draw back of higher cost compared to passive filtering techniques. Consequently, the passive harmonic filtering techniques to a large extent are still the most commonly used techniques for current harmonics mitigation of 6-pulse front-end diode rectifier
Here in ACE we have developed an efficient passive broadband filter, which can suit many similar of loads. Since all filter components are passive they are rugged, maintenance free, reliable and low cost. Moreover, the filter implementation procedure is relatively easy.
