Pulse Electronics Launches High Isolation Surface Mount Gate Drive Transformer Series
SAN DIEGO—Electronic components provider Pulse Electronics Corporation recently announced that its Power Business Unit (power.pulseelectronics.com) has expanded its line of high isolation gate drive transformers with a new surface mount series using its patented Sidecar package.
According to a release from Pulse Electronics, the PH9400 series provides isolation in MOSFET and IGBT drivers in industrial applications, such as motor drive circuits and solar inverters, and for power supplies for a range of medical devices. The series offers a surface mount technology (SMT) alternative to the existing THT P058xx series while increasing the volts-second capability by up to 300 percent, the company said.
“Pulse’s patented Sidecar package has the coil inserted at one end of an open package, with the high isolation pins placed at the other end,” said Gerard Healy, product manager, Pulse Electronics Power Business Unit (Pulse Power Division), in the release. “This configuration isolates the coil from pins, achieving a greater creepage distance between them. This compact construction allows for a larger core to be used, thereby increasing the volts-second capability, while reducing the size and increasing the creepage distance by 50 percent in comparison to the existing THT solution.”
Pulse’s PH9400 series is being tested to a constant working voltage of 600Vrms and beyond. Basic and reinforced insulation versions are offered that are compliant with IEC 60950, IEC 61558, and IEC 60601, according to the company.
Pulse Electronics (pulseelectronics.com) serves the wireless and wireline communications, power management, military/aerospace, and automotive industries.
