5.2 Parasitic Capacitor Voltage in VSC

[@AnanthaKeshava]

The 5.2 and 5.3 both are great lectures on common mode phenomenon in grid-tie inverters, the depth which is hard to find anywhere else. Thank you very much.

The box equation would be Vo-Vdc/2=Vo' I feel. Then Vcg=Vg/2 - which would implicate that the common mode voltage is getting imposed by the grid on to the inverter.

Great knowledge shared regarding parasitic voltages

[@sandeep_maloth]

thank you sir

[@SunFinderApp]

Great explanation. Would it be possible to attach the ltspice ASC used for the simulations?

[@AnanthaKeshava]

For Unipolar Switching: The box equation shown Vo-Vdc=Vo'. and finally Vcg= (Vg/2-Vdc/2)+Vdc. I feel that the box equation should be : Vo-(Vdc/2)=Vo' [Adding previous two equations would result in 2Vo-Vdc=2Vo'] and Vcg=Vg/2.

sir at 21.27, vo is equal to vo'+vdc/2

[@sandeepanand8661]

Yes. thanks for pointing it.
