Back of the envelope calculations of inverters’ conduction losses (Approximate)

[@k7iq]

Sam, good to see you are getting a lot of great videos done while this pandemic has us mainly staying at home. I hope you and your family are staying safe in Israel ! Obviously YOU are doing OK ! I am working from my basement lab here in Washington state.

Hi Bob, Thanks for concern. We and family are OK only now starting to get outdoors. I have been working from distance and was surprised to find out that I am working much harder and much longer as opposed to visiting in person the companies I am consulting to. I am flooded with Zoom, Teams Skype etc. meetings all day long and into the night. AS for the videos I am already trained and it does not take me too much time from start to finish and most of subjects are related to things that pop up in my work. Take care. I guess the situation in Washington state is not that bad as on the East cost. Keep safe.

Thanks for comment. Inductors between inverter and motor can help combat EMI, primarily CM.

Good, Sam ! :) Thanks

[@leelee-ss5ic]

Thank you very much, sir!

[@sambenyaakov]

Thanks

[@justinn771]

Thank you always sir.

[@sambenyaakov]

Thanks. You are quick😊

[@sam7901]

Thank you Sir. In motor control applications, since the load is inductive, can we say that switching losses will also be small, since the current lags the voltage, therefore at steady state, it will be ZVS switching ?

[@sambenyaakov]

No, no ZVS. Look at it like each leg is like a Buck

[@sam7901]

Thank you Sir. I hadn't thought of it in that way.

What if we had introduced a coupled differential inductor between motor and inverter , which is optimized for 1Khz range. Would it be helpful?. Of course overall cost will be higher. But, does it have any advantage in terms of efficiency and reliability. Regards.

Thanks sir ...if you can make analog & digital control of switch mode power supply video series it ll be really helpful for us.

[@sambenyaakov]

Have a look at my KZbin videos on subject. e.g. kzbin.info/www/bejne/gmSwg6F7jsmcbsk
