Magnetically modulated d-c to d-c forward converter power supply

A magnetically modulated d-c to d-c feed forward converter comprising:

• a source of input d-c voltage;
• an output transformer means connected to said source of input d-c voltage, said output transformer means having a primary winding, a reset winding and at least first and second secondary windings;
• a switching transistor means connected in series with said primary winding and source of input voltage;
• said switching transistor means haing a control electrode;
• an output rectifier means connected to said first secondary winding and filter means connected to said output rectifier means to produce a filtered output d-c voltage;
• clock pulse generator means producing a pulse train for repetitively turning on said switching transistor means;
• coupling circuit means for coupling said clock pulse generator means to said control electrode;
• said coupling circuit means including a saturating transformer core coupled to said second secondary winding and being driven from its residual flux density to saturation flux density by the output voltage of said second secondary winding, whereby said switching transistor means is repetitively turned on for a cycle time starting with a clock pulse from said clock generator means and ending when said saturating transformer core reaches saturation flux density;
• said reset winding connected in bypass-circuit relation with respect to said switching transistor means and resetting the flux of said output transformer means following the saturation of said saturating transformer core.
