The harmonic filters can be categorized into three categories, i.e., passive filters, active filters, and hybrid filters. The passive filter has passive components like a resistor, inductor, and capacitor. The active filter is designed using semiconductor devices like IGBTs. Hybrid filters are a combination of active and passive filters.
