Polarity of Resonant Converter Output?

[john-boom]

In an RLCA resonant converter, will the sine output always be bipolar, centered vertically around 0V, regardless of whether the square wave is bipolar or unipolar?

Or, if the square wave is unipolar (positive only) will the sinewave also be unipolar (positive only), having a unipolar voltage amplitude?

One side of the signal path is ground - how can it be bi-polar?

You can separate the square wave into a DC component and an AC component (superposition theorem). Then look at teh RC filter, what it does to the different componnets. Lastly add the filtered components to get the output signal.

When the voltage source V1 is bipolar ...
