Vishay's New Planar Transformer Is More Efficient and Space-Saving Than Traditional Winding Technology

By WPG AmericasMay 20, 2016

Vishay Intertechnology, Inc., one of the world's largest fabricators of discrete semiconductors and passive electronic components, has always set an example of technology realization and yet again, they have proven their excellence. The company has unveiled a new Planar Transformer using the Planar Electro magnetics replacing the comparatively bulkier transformers that worked on the traditional winding technology.

Earlier, transformers used winding technology which required space, making the transformer more capacious. The Planar transformer delivers power from 1 kW to 3 kW which is approximately correspondent to the earlier one. The working frequency of this latest device ranges from 50 kHz to 400 kHz with excellent repeatability, although the elimination of windings has reduced the overall size of the transformer to 70 mm by 53 mm by 22 mm.

The smaller size saves space in the working sub-assemblies. Furthermore, the weight of the transformer has been cut down to merely 170 grams making the device extremely convenient to use. The Planar transformer can withstand temperature from -55oC to +125oC with the ability to dissipate the extra heat. The inductance range of the device varies from 49uH to 1500uH.

The device is offered in full-bridge, half-bridge and forward power supply topologies. It offers fast and easy connection, thanks to its tapped outputs. The device is RoHS compliant and does not contain any hazardous material. Moreover, Vishay will provide customization options to meet your individual needs.

The Planar transformers would extensively be used for the following applications:

  • DC/DC power converters
  • On-board chargers for electric vehicles
  • UPS
  • Power control cooling units
  • Solar inverters

The production of the devices will begin in early fourth quarter of 2016.  Lead time for production quantities will be approximately 12 weeks for the PLA51 devices.  Samples of the PLA51 are available now and are available to customers for testing purposes.

With their ability to anticipate market demands and customer expectations, Vishay Intertechnology has always been a step ahead in innovations. They have manufactured some of the best and most effective electronic components like diodes, MOSFETs, and infrared optoelectronics. Further, they are experts in making finest quality resistors, inductors, and capacitors. These components have been extensively used in nearly all types of electronic devices and equipment in assorted industries like automotive, telecommunications, military, aerospace, power supplies, computing industries, medical markets, and others.
