Power Integrations Releases New Version of PI Expert Power Supply Design Software

Power Integrations has launched Version 7.1.5 of its popular PI Expert power supply design software. Available now for free download from the Power Integrations website, this revision of the design tool includes a number of enhancements:

  1. Provides improved support for Power Integrations' HiperPLC controller IC for offline resonant converters. The software permits the designer to choose from a variety of magnetic core materials and sizes for both for the LLC and PFC stages. The design spreadsheet allows for transformer design optimization for improved efficiency.
  2. Accurately calculates the external resistor (REXT) required to reduce no-load consumption in designs using PI's LinkSwitch -II and LinkSwitch-CV product families in flyback topologies.
  3. Expands the Help feature to include traditional Chinese language support.

Peter Vaughan, director of applications engineering at Power Integrations, comments: "Design engineers are increasingly challenged to optimize their power supply circuitry for efficiency, performance, and size. New efficiency standards are very demanding and do not allow any margin for less-than-optimal circuit design and component selection. We are constantly refining PI Expert to ensure that it addresses the latest industry demands, allowing design engineers to deliver efficient power supplies that are right first time."

PI Expert Suite v7.1.5 is available now on the Power Integrations website at ww.powerint.com/pi-expert.
