Active Harmonic Filter

SNA-AHF series active harmonic filter is a new type of power quality improvement production for dynamically filtering harmonics and compensating reactive power. It can filter and compensate harmonic (variable in orders and frequency) and dynamic reactive power in real time. It is used to overcome the shortcomings of conventional harmonic suppression and reactive power compensation methods such as passive harmonic filters, and achieve the harmonic filtering function and reactive power compensation function of the system.

SINAVA POWER's Active Harmonic Filter (AHF) is an advanced solution designed to address harmonic distortion in power systems, ensuring a stable and high-quality electrical environment. The AHF is a highly efficient and flexible tool for mitigating harmonic interference, suitable for a variety of industrial and commercial applications. This active filter continuously monitors the load current and rapidly reacts to the changes in power system distortion, injecting corrective currents to neutralize unwanted harmonics from the upstream power source.

By deploying this cutting-edge technology, SINAVA POWER AHF ensures improved power quality, with more balanced voltage and current waveforms, and helps to comply with strict harmonic limits. The system can handle compensation up to the 51st order of harmonics, balancing load between phases and the neutral, which results in enhanced operational efficiency.

Key Features of SINAVA POWER Active Harmonic Filter include:

- Harmonic compensation up to the 51st order

- Load balancing across phases and neutral

- Compact design with a three-level topology

- Expandable up to 12 modules in parallel for scalable solutions

- User-friendly 4-inch/7-inch/10-inch Human-Machine Interface (HMI)

- Silent operation ≤65dB(A) for a noise-free environment

- Optional RS485/Ethernet communication for easy integration into existing systems
