Complete the Last Piece of the Puzzle for APF Applications

The SuperPQ APF series of stabilized active power filters is characterized by its rapid response capabilities and accurate resonance avoidance. Its standout feature is the concurrent mitigation of a spectrum of unstable harmonics, which contributes to the stabilization of the electrical grid.

▶The advantages of SuperPQ APF

■ The advantages of a stabilized Active Power Filter

■ Simultaneously compensating for Total Harmonic Distortion of Current (THDi) and Total Harmonic Distortion of Voltage (THDv).

■ Capable of managing interharmonics, even-order harmonics, and transient harmonics, among other unstable harmonics.

■ The risk of resonance is mitigated by optimizing hardware configurations and algorithms.

■ Mitigation of Load-Side Harmonic Currents

■ The switching frequency can reach up to 80 kHz

■ The response time is less than or equal to 1 millisecond

▶Challenges in the application of traditional Active Power Filters (APF)

■ Only harmonic currents can be mitigated, not harmonic voltages.

■ In weak grid conditions, voltage distortion is generally high, and Active Power Filters may not operate effectively.

■ It is not feasible to mitigate complex harmonics such as interharmonics, even-order harmonics, and transient harmonics.

■ Prone to resonance

■ The impact on improving load-side harmonic current is minimal.
