DYNAMIC COMPENSATION HARMONIC

Sinexcel Active Harmonic Filter can realize 2nd to 50th harmonic compensation, compensation ratio can be set selectively by the customers, output compensation current follows the system harmonic variation, devoted to green power quality.

Different loads generate variety harmonic content which changes dynamically during different working conditions.

SINEXCEL UNIQUE

Intelligent Fast Fourier Transform

One of the biggest characteristics of Active PQ solution is to use information technology to manage energy. With the characteristics of high accuracy and high speed of computing power, empower users PQ will obtain continuous, stable and infinitely close to the highest energy efficiency of power energy.

Intelligent FFT is an iterative FFT algorithm based on Sinexcel updated computing power and ten years of experience in field harmonic waveform database.
  • Harmonic current decomposition
  • AHF outputs compensation current
  • 01
    AHF synchronously allocates the compensation capacity in real time
    AHF self-learns the system impedance characteristics, identify feature of individual harmonic order
    02
    AHF detects the resonance point, stops compensating at this point to avoid amplify resonance, realizing the system protection.
    AHF continues to compensation other order harmonics, real time monitor the resonance points.
    03
    When the system load changes and the resonance point changes, AHF starts the process of self-learning, self-adaptation and self-adjustment again. 

    SINEXCEL Earliest ADOPTER

    3-level Topology

    · One more output level, less ripple current content

    · Output PWM waveform is more similar to sinusoidal wave, better harmonic compensation effect

    · The volume of LCL filter is reduced, beneficial for AHF module design

    · Less inductance loss, improving the system efficiency

    · IGBT withstand voltage stress cut into half, effectively reduce the switching loss

    · Less switching loss of IGBTs, more thermal margin, higher switching frequency

    SINEXCEL PIONEER

    Modular design

    Ultra-compact design, wall and rack-mounted structure and fine capacity distribution can fully meet customers' needs, suitable for space limit application, retrofit projects.

    Convenient for transportation and replacement, easy to be integrated into panel.

    TEN YEARS ITERATION

    independent air duct design

    Upper and lower layer design, IGBT heatsink and inductor, which account for most heat of AHF, are concentrated in the lower layer, forcing air cooling, fast heat dissipation, and do not affect the upper PCBA

    Upper PCBA auxiliary air duct design, expansion of heat dissipation channel, wide angle heat dissipation
