Active Harmonic Filter Read this case study of the advantages and disadvantages of the active harmonic filter and how passive filter installation removes harmonics, voltage surges and improves PF. Fig. However, passive filters have the following drawbacks: 1) Filtering characteristics are strongly affected by the source impedance 2) Amplification of currents on the source side at specific frequencies can appear due to the parallel resonance between the source and the passive filter For a single pole low-pass filter, fc = 1/ (2 × π × RC) the filter roll-off is 6dB per octave or 20dB/decade. So its output signal’s amplitude is always less than it’s input signal’s amplitude. Filters can be divided into two distinct types: active filters and passive filters. » There is always someloss of signal, It can be in the passband. A frequency filter or also known as a frequency selective circuit is a special type of a circuit, which is used for filtering out some of the input signals on the basis of their frequencies. These points need to be taken into account when undertaking the design and it may be necessary to mitigate against some of the effects if they are used. Advantages: • No resonance issue • It can eliminate any harmonics • Used for voltage regulation • Used for reactive power compensation • It provides reliable operation Disadvantages: • It is expensive • It provides complex control systems.

Like any approach taken within electronic design, there are advantages and disadvantages. The adjustable parameter in designing of filter, the gain ripple is expressed in dB. Ideally Filter alters the relative amplitudes of the various frequency components and the phase characteristics and its ‘Gain’ depends entirely on the signal frequency. Active vs Passive. Conventionally, passive filters consisting of tuned L-C filters have been used to suppress harmonics because of their low initial cost. They can handle large voltage currents and power, There is no limitation on the frequency range, They do not need the additional dc power supply for their operation, There is no isolation between input and output, The circuit becomes bulky if inductors are used, There is always some loss of signal it can be in the passband, There is no clear demarcation between passband and stopband but actually, it gets mixed up. (Fig 3. A filter circuit passes some frequency signal’s without any attenuation (Reduction in amplitude) or with some amplification, & attenuate other frequency depending on the types of the filter. The main function is to filter out the dust, odor and contaminants in the air. No amplifying elements. They do not need the additional dc power supply for their operation.
