MTE Corporation introduced the SyntriX AHF on September 22, 2025. This active harmonic filter incorporates silicon carbide power semiconductors, a development that MTE states delivers over 99% system efficiency. The target applications include data centers, manufacturing facilities, renewable energy installations, and transportation infrastructure. These sectors frequently contend with variable frequency drives (VFDs) that elevate total harmonic distortion (THD) beyond the thresholds set by IEEE 519 standards.
Technical Specifications
The SyntriX AHF addresses harmonics up to the 50th order. Its response time is reported as sub-50 microseconds, allowing it to simultaneously correct multiple harmonic signatures originating from sources such as 6-pulse VFDs, EC fans, and LED lighting. The filter’s design is modular, scaling from 50A to 450A and beyond without requiring hardware modifications. MTE reports this modular form factor is 30% smaller than previous active filter designs. The unit operates on 3-phase, 3-wire systems up to 480V. Power factor correction to unity is also a feature, with a stated capability of plus or minus 1. Users can monitor operations via an integrated 4.5-inch human-machine interface (HMI) or an optional 7-inch external HMI.
Whats Genuinely New
The primary advancement in the SyntriX AHF centers on its adoption of silicon carbide (SiC) power semiconductors. Compared to traditional Insulated Gate Bipolar Transistors (IGBTs), SiC devices reduce switching losses by approximately 30%. This efficiency gain translates to less heat generation, a reduced need for cooling systems, and potentially extended equipment lifespan. MTE President Ahsan Javed commented that the SyntriX “enables customers to operate with greater efficiency, reliability, and confidence in mission-critical environments.” The reported 99%+ system efficiency signifies less than 1% of processed power is lost across the filter’s harmonic correction range.
Why It Matters
The active harmonic filter market is projected to grow from $760 million in 2025 to $1.11 billion by 2030, a compound annual growth rate of 7.8%, according to MarketsandMarkets. A significant driver for this growth is the widespread deployment of VFDs in HVAC, compressed air, and conveyor systems. Approximately 62% of manufacturing facilities exceed the IEEE 519-2022 THD limits without mitigation equipment. The updated IEEE 519-2022 standard, which introduced tighter current distortion limits at the point of common coupling, is prompting utilities to enforce compliance, thereby accelerating the adoption of active filters. Data centers, in particular, are a growing segment for these devices due to the nonlinear current draw of server power supplies. The SyntriX AHF offers parallel harmonic compensation without interrupting the protected circuit, a benefit for retrofit installations where space for passive filters is limited.
Critical Perspective
The SyntriX AHF’s use of silicon carbide comes with a cost premium compared to IGBT-based filters. While MTE reports over 99% efficiency, the precise delta in efficiency compared to leading IGBT competitors like Danfoss and ABB requires further substantiation. The product targets compliance with IEEE 519-2022 THD limits, which are 5% at the point of common coupling for general systems. However, the real-world field track record of the SyntriX AHF remains to be established. Competitors such as Schaffner also offer active harmonic filters, presenting a competitive landscape where MTE must demonstrate its product’s performance and reliability.
