ABSTRACT:
A pulse duty control system comprises a pulse duty controlling element including a core made of an amorphous, magnetically soft material having a first and a second coil disposed thereon. A first set of pulses are applied to one end of the first coil while a second set of pulses, which are phase displaced by 180.degree. from the first set of pulses, are applied to one end of the second coil. The other end of the first coil is connected to an output terminal while the other end of the second coil is connected to a current controlling transistor, the base of which is connected to control circuit means. An output pulse, which is developed at the other end of the first coil, has a rising edge which lags behind the rising edge of a pulse of the first set of pulses by a time delay corresponding to the degree of conduction of the transistor which in turn depends on an output voltage from the control circuit means. The output pulse has a falling edge which is substantially synchronized with that of the pulse in the first set of pulses.
