GaN-Ready Magnetics Suit Next Gen Power Conversion Technologies


Precision, Inc. announces the global launch of the company´s GaN-ready magnetic capabilities. GaN-ready LLC transformers and PFC inductors are now available for a broad range of applications including, power factor correction, server, solar, automotive/HEV, industrial motor drives, and power supplies/UPS.

GaN switches provide an impressive number of key benefits to design engineers including:

·      Significant reductions in system volume, weight and size

·      Higher operating temperatures / reduced heat sink requirements

·      Lower switching losses / increased power output (up to 95% peak efficiency)

·      High breakdown strength, high maximum current and high oscillation frequency

Precision has partnered with GaN experts including International Rectifier and Transphorm to create ultra-compact power supplies with LLC transformer and PFC inductor technologies designed for optimum performance at high switching frequencies. Precision brought unique expertise in core material selection and parasitic (i.e., leakage inductance and capacitance) management together with an extensive Litz wire selection to cutting edge GaN technologies that are now available worldwide.

Precision provides other custom GaN-ready magnetics in both PFC and LLC formats directly to design engineers and has partnered with both Transphorm and International Rectifier on large circuits with integrated GaN-ready magnetics.

The EZ-GaN Evaluation Board All-in-One Power Supply from Transphorm is a complete high-density 250 W computer power supply using 600 V GaN HEMTs switching at 200 kHz. The system provides up to a 45% reduction in size compared to an Si-based equivalent with a
