Abstract - This application note describes the possibilities to improve multi-pulse drives by applying relatively small Active Filter to the installation. Multi-pulse drives have several problems that causes them to behave like a non-ideal multi-pulse drive, e.g., the 5th harmonic is not fully eliminated. By using a well-tuned Active Filter inside the Multi-pulse drive, the drive can be adjusted to have a perfect multi-pulse behavior. It furthermore gives the opportunity to compensate the residual harmonics of the drive with the available capacity of the Active Filter. These improvements can be achieved even by retrofitting an Active Filter into existing multi-pulse drive applications.
