On March 5, 2019, Power Integrations, a leader in medium and high voltage inverter applications, introduced a series of magnetic isolation transformers that provide the correct voltage and power for the company's SCALE-iDriver? series of gate drivers. The combination of the two provides a simple, stable and cost-effective DC-DC converter solution that requires no additional voltage adjustment, reducing system cost and development time. This SIT12xxI transformer and SCALE-iDriver IC are fully UL and VDE certified.

The new SIT12xxI transformers feature an innovative insulation construction that improves reliability, providing high insulation combined with low coupling capacitance. The device is suitable for 600 V and 1200 V, dual-channel SCALE-iDriver gate drivers with 5 V (SIT1253I) or 15 V (SIT1217I) input voltage and 25 V output voltage. Weighing only 9 grams, this cased transformer can pass field life extension and high-level vibration and shock resistance 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 Gate Drivers at Power Integrations, said: "The SCALE-iDriver family of IGBT and SiC-MOSFET driver ICs uses Power Integrations' FluxLink™ magnetic inductive bidirectional communication technology to ensure reinforced electromagnetic isolation between the primary and secondary sides. , thereby setting a new standard for insulation integrity and reliability. By offering perfectly matched transformers, we reduce system development, compliance and certification time, while simplifying the purchasing process. The new design of the transformer construction is suitable for industrial applications, while providing a robust A lightweight, isolated DC-DC solution that minimizes common-mode noise coupling.”
