Regulated voltage converter which has substantially fewer parts than prior art devices

A switching power source device comprising:

• an input d.c. power source, an oscillating switching circuit connected at the output of said input d.c. power source, a saturable reactor transformer with first, second, third and fourth windings and said first winding receiving the output of said oscillating switching circuit, said second and third windings connected to supply inputs to said oscillating switching circuit, a power source transformer with primary and secondary windings, and a capacitor connected in series between said primary winding and said first winding, and a control circuit connected between the secondary winding of said power source transformer and said fourth winding of said saturable reactor transformer.
