Thanks for your reply!What type of signal do you want to isolate? Analog, digital, power - ?
AND ... ? ? ?I would isolate Digital PWM signla .
Thanks @Janis59 @Irving @AnalogKid for your responses.AND ... ? ? ?
Think. What would an experienced circuit designer need to know about my application in order to give free help without having to pry the details out of me ... ?
Signal frequency?
Min and max PWM duty cycles?
Input signal amplitude?
Output signal amplitude?
Peak isolated voltage difference between input and output?
Power sources for the input and output sides of the circuit?

This is standard power converter territory.Thanks @Janis59 @Irving @AnalogKid for your responses.
I have attached my system block diagram for elaborating my question.
Short summery of Project:
I am desired to auto-tune tank circuit between amplifier and ultrasonic transducer to power it effeciently and reduce losses. I have freedom to varing capacitor only and to keep the inductor value minimum (constant) in order to reduce EMI of inductor (which can influence MRI (performance), used along with ultrasonic transducer). A PWM control signal is used to control Variable capacitor such that amplifier power is exacely matched with transducer. A robust isolation technique is resquested which can isolation AC switch driver(5V) from Control switches (260Vp-p).
