Advancements in electrification are bringing new demands upon design engineers as they grapple with higher power requirements and the need for more sophisticated protection from electromagnetic interference. Two new products from power solutions manufacturer Astrodyne TDI address both areas.
Leveraging its recent acquisition of Powertronix, as reported previously in Magnetics Magazine, a new range of toroidal current transformers is designed to elevate the accuracy and efficiency of current measurement, circuit control and power monitoring. They provide gap-free performance with low-noise operation, making them ideal for safeguarding and regulating modern electrical systems.
They come in 6.5” and 7.5” models and feature a broad operational range. They can handle primary currents from 50 amps to 6,000 amps and rated voltages up to 600 volts. They support frequencies between 50 Hz and 400 Hz, with secondary currents set at 5.0 amps, making them suitable for a wide variety of applications.
More power typically means higher current, which results in higher costs (more copper) and higher power (I2R) losses, often making designs unviable. One way to resolve the conundrum is to boost the input AC voltage (760 – 1000AC), thus delivering the same amount of power without significantly impacting power losses.
Astrodyne’s RP395 3-phase delta 1000 VAC EMI power line filter is designed to support the new generation of power conversion systems utilizing high-voltage AC. The series supports currents ranging from 150A to 2500A, offering OEMs adaptability for different power levels and delivering superior insertion loss performance against electromagnetic interference. A 3500A design is also being developed. They are well suited for hydrogen generation electrolyzers, energy and battery storage systems, high-current rectifiers, high power inverters and megawatt chargers. See www.AstrodyneTDI.com.
