1. Circuit diagram.

enter image description here

2. Position of Q-point : At the center of dc 1 outline.

3. Operating cycle: Circuit operates for entire 360˚ of input signal.

4. Power efficiency: Maximum efficiency (for series fed ) = 25%

Maximum efficiency for transformer coupled = 50%

Class …
