Active filters (APFs) such as the SMARCTIVE use power electronic devices such as IGBTs (insulated gate bipolar transistor) to reduce harmonic distortion in the power system. IGBTs are used in active filters for several reasons:
High frequency switching: IGBTs have a fast switching speed, which allows them to respond quickly to changes in harmonic distortion in the power system. This allows the APF to effectively filter out harmonic frequencies.
High power handling capability: IGBTs can handle high power levels, which is important in active harmonic filtering applications where harmonic distortion can be significant.
High voltage rating: IGBTs have a high voltage rating, which allows them to handle the high voltage levels that are present in power systems.
Efficiency: IGBTs are more efficient than other types of semiconductor devices, such as thyristors, which reduces losses and heat generated by AHFs.
Cost-effective: IGBTs are a cost-effective option for active harmonic filtering, are not as expensive as other power electronic devices and are widely available.
In general, IGBTs are well suited for active harmonic filtering applications because they have fast switching speeds, high power handling capability, high voltage rating, high efficiency, and are cost-effective. These characteristics are crucial to the accurate and efficient operation of an active harmonic filter system.
