Compare IGBTs from Different Makers under expected Operating Conditions
ezIGBT announced the release of a powerful set of 'compare' toolset to its online calculator to help designers in selecting the right IGBTs for specific applications, leading to more reliable products, better efficiencies and lower costs. ezIGBT specializes in publication of online aids that help designers of motor drives, UPSs, solar inverters, industrial power supplies, etc. produce energy-efficient systems. With the release of their 'compare' toolkit, they are in the second phase of helping power converter designers compare discrete IGBTs from different manufacturers.
Using the online calculator, the current tool release, allows power system designers to: Compare 3 IGBTs for the Vceon and Ets at the designer’s expected junction temperature (Tj); Calculate power loss vs pwm frequency at user’s junction temperature and application condition for duty cycle; and Predict the heatsink size (Rthsa) for the IGBT. The tool also allows the graphs and data generated during this simulation to be downloaded. This feature needs the user to subscribe to the site and no passwords are needed at this time.
More new tools coming soon would allow the power electronic system designer to: Compare the split in losses between the IGBT, the copak diode in conduction and switching loss components so the switch/ system pwm choices can be made with more data; and Compare the I (current) versus f (frequency) curve for the user’s conditions. Users can go to ezigbt.com to subscribe for updates when new tools and IGBT models are added to the website.
The online calculator from ezIGBT is designed to be helpful when comparing IGBTs for specific application conditions. Since datasheets provide guidance only for limited min and max operating conditions, designers need extra help in predicting and comparing the total losses of IGBTs in specific applications conditions. The online toolset from ezIGBT solves the problem for designers by helping them to compare suitable products based on device and performance comparison. The designer is able to pick up the right device for the application through a series of easy to use tools. The calculators use standard default parameters to speed up the calculation but the user is allowed to edit most fields for their specific needs.
