    Lightbulb How to design base drive transformer? especially the primary winding

    I have no idea about the push - pull proportional base drive transformer design.

    the transistor of the secondary winding is 2SC3320.

    I think the primary current is about 4A.

    magnetic core:EE22

    Vcc:12V frequencey:25kHz

    primary ,secondary,feedback turns : 34T/34T/9T/9T/2T

    I am so sorry My English is so poor.Does anyone can tell me how to calculation the windings?,Please...
