DC-DC converter in which the duty factor is controlled by the capacitor voltage [articol]

Abstract

The d.c.-d.c. converters, which assure the conversion from d.c.-d.c., have both at the input and at the output, different values for the voltages and the continuous currents. In most cases, the output voltages must remain constant when the input voltage and the load resistance change within certain limits. The paper analyses the variation of the output voltage when the input voltage presents relatively small variations in time and suggests a PWM command solution for the minimization of these variations.
