Abstract: The duty cycle of the switching transistor in a DC to DC converter is controlled by an astable multivibrator whose alternate switching states are respectively responsive to the line and load voltages. Feedback of the output voltage to control the duration of one state of the multivibrator is obtained from the primary of the converter output transformer whose magnetic energy level is not allowed to fully dissipate in any one operating cycle. A balancing circuit arrangement is utilized to minimize variations in the base drive signal of the switching transistor and to prevent it from saturating to eliminate variations in the duration of the conducting state of the transistor due to charge storage.
