Version 7.1.5 Optimizes Transformer Design for Improved Efficiency, Accurately Calculates External Resistor Requirements, and Includes Traditional Chinese Language Support.
Power Integrations, the leader in high-voltage integrated circuits for energy-efficient power conversion, today launched Version 7.1.5 of its popular PI Expert power supply
— Provides improved support for Power Integrations’ HiperPLC(R) 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.
— Accurately calculates the external resistor (REXT) required to reduce no-load consumption in designs using PI’s LinkSwitch(R)-II and LinkSwitch-CV product families in flyback topologies.
— 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
PI Expert Suite v7.1.5 includes:
— PI Expert: This interactive program takes a designer’s power supply specifications, automatically generates the electrical design, and selects the critical components required. It also provides a detailed electrical and mechanical transformer design using PI’s proprietary E-Shield(TM) EMI reduction techniques. Optimization choices stressing cost and efficiency are included to help designers target specific needs. The program reduces design time from days to minutes.
— PI Xls Designer: A hands-on approach to power supply design for advanced users and those who prefer a spreadsheet interface. The tool generates detailed engineering and mechanical designs to assist users in prototyping the transformer.
— PI Viewer: A tool for viewing design files created with older versions of PI Expert.
PI Expert Suite v7.1.5 is available now on the Power Integrations website at www.powerint.com/pi-expert.
