UCC25600 for AC output

Ed Walker

Can the rectifier diodes be removed to provide an AC high voltage output to drive a SONAR element?
It seems possible to produce an AC output, the exact frequency would be dependent on the operating point on the resonant curve.
Are there any examples of AC outputs with this resonant controller?

The AC output of the LLC will be a square wave voltage, while the current will be sinusoidal (or close to sinusoidal). We do not have any examples of such a configuration.

Make a small Class D amplifier with the reference freq as you want.

Tried to filter the output voltage of the LLC to a sinusoidal? A LC filter would be best.
