Passive Harmonic Filters are generally more cost-effective, whereas most of the other filtering techniques tend to have the common drawback of higher costs. Consequently, the 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 application. We have developed an efficient Passive Harmonic Filter system, which can suit many such similar loads. Since all filter components are passive they are rugged, maintenance free, reliable and low cost. Moreover, the filter implementation procedure is relatively easy - Electronic Solutions.

High pass passive harmonic filters are used to eliminate higher order harmonics and to have flexible control over the wide range of frequencies. The basic high pass harmonic filter design use three passive components, resistor, capacitor, and inductor. Passive filters work by exhibiting different impedance values at the resonant frequency. Power factor correction needs a design to compensate reactive power demand & inject harmonic currents through the equipment into the power supply system. Generally, power supply systems in industries include a capacitor bank & an arrangement of tuned filters. Analysis of communication between harmonic filters & capacitor banks in the power supply system of the industry is carried out. A passive filter component is a combination of capacitors and inductors that are tuned to resonate at a single frequency, or through a band of frequencies - Electronic Products Melbourne.

Designs without consideration of the above identified criteria possibly result in poor filter performance and over/ under rated filter designs. The main difference between these two types of harmonic filters is the components used for the filter design. Passive harmonic filters use simple passive components mainly resistors, inductors, and capacitors. Whereas active harmonic filters use active components such as different types of integrated circuits. The nonlinear loads draw current from the power line that is not in a perfect sinusoidal waveform. The nonsinusoidal current waveform can be a complex series of simple sinusoidal which can oscillate at an integer, multiple of the power line fundamental frequency. Whether in industrial settings, commercial buildings, or renewable energy installations, these filters play a pivotal role in ensuring the smooth and efficient operation of critical systems.
