Hi,

As we know that PWM converters use IGBT to produce AC signal from DC constant voltage.
To set carrier frequecy high wolume means better AC signal, but high carrier frequency oparate switchs more, therefore switching lost is produced.
I would like to find out detail information about lost.

thanks

Hello again, Hanifi.

You could have used the GOOGLE search engine to research your question.

If you had, you would have found many articles and informative documents that would answer your question for you.

If you will click on the link below, you will see what I am suggesting.

Within the reported results, you will find the following technical paper :

IGBT Switching Losses

If you click on the title above, it will take you to the technical paper.


For future reference, I would suggest that when you have questions of a general nature (rather than a specific nature) that you take advantage of search engines such as GOOGLE before posting your questions in this forum.


Kind regards,
