1. Harmonic Elimination: This is achieved by using converters that produce fewer harmonics, such as six-pulse or twelve-pulse converters.
2. Harmonic Filtering: A passive filter can be used to remove specific harmonics from the output current or voltage.
3. Pulse Width Modulation (PWM): By controlling the pulse width of the switching device, the harmonic content can be reduced.
4. Active Harmonic Filters: These are active circuits that generate a current or voltage waveform that is designed to cancel out specific harmonics in the output.
