## Electrical tools (MS Excel Spreadsheets)

This section is dedicated to tools every electrical engineer can use in daily work. These spreadsheets below will make your job much more easier, alowing you to shorten the time used for endless calculations of cables, voltage drop, various selctions of circuit breakers, capacitors, cable size and so on.

Most of spreadsheets are developed by two electrical engineers and programmers **mr. Jignesh Parmar** and **mr. Hemant Kashikar**. They all really did an awsome job, you must admit.

Just to mention that all calculation spreadsheets are ** free** for download! 😉

Hi, can you please help me with writing the code for calculating switching losses in an IGBT with unity power factor.I m suppose to use time slicing technique and estimate losses or switch state at 1000 time instants.

Can you help?
