SOFTWARE TOOLS: Power Integrations has new version of its Power Supply Design Software

San Jose, Ca. – Available now from Power Integrations is the newest Version 7.1.5 of its PI Expert power supply design software.

Available now for free download from the Power Integrations website, this revision of the design tool includes support for Power Integrations' HiperPL? 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.

It also now 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.

According to Peter Vaughan, director of applications engineering at Power Integrations, PI Expert Suite v7.1.5 includes PI Expert, an 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 EMI reduction techniques.

Also included is PI Xls Designer, for advanced users and those who prefer a spreadsheet interface. It generates detailed engineering and mechanical designs to assist users in prototyping the transformer.
