nobody talking about switching PS wasting power on input filter caps?

But this motor will works to stop your generator, it won't works to keep rotation.

So, you're think that AC source will not consume energy from capacitor? :)

IT DOESNT!!  |O This *electric motor* GIVES back the energy to the *mechanical motor* just as before the "electric generator* TOOK energy from *mechanical motor*  :horse: :horse:

Again, there are two options:

1) you're right, LTSpice works wrong and there is no power consumption by AC source from capacitor

2) you are wrong and AC source consumes power from the capactor as it shown in LTSPice

I'm completely agree with LTspice and I think that AC source consumes power from capacitor. What is your choice?

Previously you're said that there is no power loss due to capacitor. Let's clarify things step-by-step.

First answer - do you agree that AC source consumes power from the capacitor? Yes or no?

Now integrate the power over time.

it will be zero.

But you didn't answered on the question. Do you agree that AC source consumes power from the capacitor? Yes or not?
