      Ultra High Efficiency
      Performance breakthrough brought by SiC technology
      Silicon carbide (SiC) MOSFETs achieves ultra-high efficiency primarily due to their wide bandgap, which leads to lower on-state resistance (Rds(on)), faster switching speeds, and reduced switching losses. These properties enable SiC MOSFETs to operate at higher frequencie and temperature with improved overall performance, resulting in more efficient power conversion systems
      What benefit will be brought to user with 99% ultra high efficiency?
      Electricity bill saving, higher ROI

      Tiny dimension but huge capacity
      Performance breakthrough brought by SiC technology
      High heat resistance, high thermal conductivity, and high switching frequency, these advantages of SiC bring lower heat dissipation and less ripple current output to Ultra Series AHF. With the physical upgrade of this key component and the 3-year deep research of the R&D team, Sinexcel realizes the ultra-high integration design in Ultra Series AHF
      Less Ventilation Requirement
      Performance breakthrough brought by SiC technology
      The drift region of SiC can be made thinner so it has high heat resistance and high thermal conductivity. This advantage make the Ultra Series AHF produce less heat so the heat dissipation is lower.

      The low thermal demands of these SiC active filter modules make them particularly suitable for use in high IP-rated cabinets. Since they require less cooling airflow, they can operate effectively within the confined and sealed environment of these cabinets without the risk of overheating.

      Enormous harmonic compensation rate
      Industry application breakthrough brought by Ultra Series
      SiC technology brings much higher switching frequecncy (the average of 40KHz and maximum up to 95KHz) to Ultra Series AHF. With the high switching frequency and Sinexcel unique algorithm design, Ultra Series AHF realizes the enormous harmonic compensate rate.

      Industry application breakthrough brought by Ultra Series
      Sinexcel Ultra Series AHF updates the software algorithm and when CTs are at the source side, this makes the AHF realizes the closed-loop design; The unique algorithm can automatically identify and correct the compensation output result, and the process without manual adjustment. The automatic fine-tuning realizes automatic adjusts THDi<5% and the whole process can be completed within one minute;

      Easy software operation, and simple hardware installation. Only power cables and a set of CT to set up Ultra Series AHF. The Automatic fine-tuning function realizes intelligent and excellent compensation effects, bringing users a simple and efficient commissioning experience.
      Resonance suppression
      Industry application breakthrough brought by Ultra Series
      Unique Intelligent Fourier Technology
      In the process of solving power quality problems, how to solve the resonance is the direction that the industry has been focusing on; when the system resonates, it will generate a voltage several times higher than the power supply. And will be applied in the capacitors, transformers, circuit breakers, and other equipment in the circuit, even causing insulation damage to high-voltage electrical equipment;


      Since 2017, Sinexcel had designed resonance suppression by the unique intelligent Fast Fourier Technology and had been the industry-leading in resonance suppression technology. This technology ensures the normal and stable operation of the system and avoids the harm of resonance for the user.


      In 2022, after several years of persistent research and development, Sinexcel’s R&D team launched the resonance algorithm 2.0. Based on resonance suppression, it broke through resonance compensation, achieved the requirement of THDi<5%, output perfect sine waves, and brought excellent power quality for the user.
      THDu mitigation
      Industry application breakthrough brought by Ultra Series
      Extreme voltage distortion can cause multiple zero crossings for the voltage wave. For equipment where proper sequencing of operations depends on a zero crossing for timing, voltage distortion can cause misoperation. And 5th harmonic voltage distortion can cause serious problems for 3-phase motors.

      Sinexcel Ultra Series AHF through the development of the voltage detection circuit to realize THDu compensation.

      And re-designed the hardware, successful to achieve the zreo CT to compensate THDu.
