Power Integrations Introduces New Power Transformer

Posted by sere on December 11th, 2019

The led driver leader in medium and high voltage inverter applications The company recently introduced a series of magnetic isolation transformers that provide the company's SCALE-iDriver ™ series of gate drivers with the correct voltage and power. The combination of the two provides a simple, stable, and cost-effective DC-DC converter solution that eliminates the need for additional voltage adjustments, reducing system costs and development time. This SIT12xxI transformer and SCALE-iDriver IC are fully UL and VDE approved.

The new SIT12xxI transformer adopts innovative insulation structure, which can improve reliability and combine low coupling capacitance while providing high insulation. The device is suitable for dual SCALE-iDriver gate drivers with 600 V and 1200 V, 5 V (SIT1253I) or 15 V (SIT1217I) input voltage and 25 V output voltage. This case-type transformer weighs only 9 grams and can pass field life extension and high-level vibration and shock tests without potting materials. They comply with UL1446, UL61800-5-1, IEC61800-5-1, IEC61558-1 and IEC61558-2-16 standards.

Thorsten Schmidt, Product Marketing Manager for Gate Drivers, said: "The FluxLink ™ magnetic two-way communication technology used in the SCALE-iDriver series of IGBT and SiC-MOSFET driver ICs ensures enhanced electromagnetic insulation between the and secondary sides, thereby establishing insulation. New standards for integrity and reliability. By providing perfectly matched transformers, we reduce system development, compliance and certification time while simplifying the purchasing process. The new design of the transformer structure is suitable for industrial applications, while providing rugged and lightweight isolation The DC-DC solution also minimizes common-mode noise coupling. "
