SWaP-constrained power factor correction chokes (PFCs) for industrial and automotive uses introduced by ITG

ELMSFORD, N.Y. – ITG Electronics Inc. in Elmsford, N.Y., is introducing the PFC433835B series of power factor correction chokes (PFCs) for high switching frequencies.

The PFC433835B series of PFC chokes is applicable for AC to DC conversion in industrial, equipment and automotive applications. The high-current output chokes can handle as much as 50 amps with approximately 50 percent roll off.

Capable of handling as much as 3,300 Watts, the PFC433835B series included CCM PFC boost converters with switching frequencies from 100 to 200 Khz.

The PFC433835B series is suitable for inductance ranges from 90 to 285 microhenries, and have sizes as large as 43 by 35 millimeters and maximum heights of 38 millimeters.

Compared with traditional toroidal-shaped PFC chokes, the small size, weight, and power consumption (SWaP) PFC433835B series features a flat wire and square core construction to save space and increase power density.

These devices are as much as 50 percent smaller than toroidal-shaped PFC chokes with similar power ratings, and their flat wire technology can reduce DC resistance by as much as 40 percent, leading to substantially lower copper losses.
