Online design centre
speeds PSU development
The myPower On-line Design Centre is an Internet-based design and simulation tool combined with overnight design kit fulfillment to cut weeks, or months of design time for advanced power systems
The myPower On-line Design Centre incorporates a free simulation tool that delivers very high accuracy (+/-5%) at very high speed (less than 5s) and provides customised design kits that are delivered within 24 hours in the Continental USA and three days overseas. Unlike other web-based design tools available today, the myPower On-Line Design Centre offers the very high accuracy needed for design optimisation, rather than idealised waveform, getting the designer as close as possible to the final electrical solution in the shortest time.

Power systems design is getting more complex as power density and system functionalities increase exponentially.
Advanced power system development times are stretching due to the lack of adequate commercially available development tools combined with the time of procuring and optimising breadboards.
"Designers resort to 'trial and error' or 'cut and paste' old designs but then struggle to meet tougher performance or cost goals.
The result is hurting the productivity of OEMs for whom power systems is a necessity but not a core competency", said Gene Sheridan, Vice-President, Computing, Communications and Appliance Business Unit, at International Rectifier.
"IR's myPower On-Line Design Centre redefines the design process for power systems and will provide our customers with a much-needed competitive edge".

Power system design complexity is specifically acute in the fast moving digital world of information technology.
The myPower Online Design Centre is now operational for DC/DC convertors operating in the range 20 to 80A currents, 200 to 1000kHz frequencies and 1.1 to 1.85V output voltages.
"The myPower On-line Design Centre is expected to expand regularly into broader areas of DC/DC convertors as well as other applications such as AC/DC convertors, appliances and lighting", added Sheridan.
Designers begin by providing their system requirements.
The myPower On Line Design Centre generates a customised design, including complete bill of materials.
Designers can run simulations to verify system behaviour, and optimise circuits for performance and cost, eliminating much of the traditional breadboarding development time.
The simulator is capable of generating waveforms for step loads, changing input voltages, steady state transient analysis and a complete AC analysis.
High accuracy provides robust designs.
The components used in the design provide some of the highest performance power systems available in the industry.
Once the designer has settled on his design, he can immediately order a customised design kit for prototyping and final production circuit development.
By incorporating nonidealised FET models and parasitics into the power system model and mathematically reducing them to a few equations with MathCAD, the Spice simulator incorporated in the myPower Online Design Centre demonstrates +/-5% accuracy while compressing computational time down to 2s.
The myPower Online Design Centre can be found at mypower.irf.com.
Use of the Online Design Centre is free.
A custom design kit includes a standard, fully assembled and tested PCB with a kit of parts to match the bill of materials.
Pricing for a custom design kit starts at US $335 each.
