The converter circuit consists of the primary winding of T901, a switching device Q901 and surge absorber
(C907,R907 and D907) which are connected to the primary winding of T901.
The oscillating signal from IC901 pin2 is applied to the gate of Q901 so that the drain - source is turned ON
and OFF. In result, the oscillating voltage is applied to the primary winding of T901.
