Hybrid Harmonic Filter
Active harmonic filter(SiC) is a new generation of active power filter (APF) designed with silicon carbide materials. Its dual-core design offers faster operation, lower losses, and higher device efficiency (>99%). In addition to dynamically compensating for harmonics, APF products can also compensate for reactive power, addressing power quality issues such as voltage fluctuations and flicker. APF products utilize state-of-the-art control technology for fully automated control, making them the preferred choice for harmonic elimination.

SiC Active Harmonic Filter is a next-generation, fully digital harmonic elimination device developed in-house by us. Compared with traditional technology, it offers distinct advantages such as faster response time, compact size, enhanced functionality, easy installation and maintenance, and straightforward commissioning. It can effectively address power quality problems with ease. APF dynamically compensates for harmonics, effectively addressing such problems as low power factor and three-phase imbalances in power quality.
The main power device adopts the next-generation semiconductor component SiC Mosfet, which offers a switching frequency greater than 100kHz, high power density, low loss, and high efficiency, with a harmonic filtering rate of up to 97%. It supports multiple compensation modes, including harmonics, reactive power, and three-phase imbalance. The PCBA is fully sealed, ensuring protection against dust, condensation, and salt spray. The device offers flexible installation options (cabinet-mounted or wall-mounted), and maintenance is straightforward.
