Abstract
A switching mode power supply where an input rectified voltage feeds in chopped mode the primary winding of a power transformer under the control of a transistor turned on by voltage pulses periodically generated by an oscillator directly fed by the input voltage and applied to the transistor through a control transformer, said transistor being turned off by a voltage pulse generated by regulating circuits fed by the output voltage of the power supply and applied to the transistor through the same control transformer which is further provided with a winding where anelectromotive force is induced which is proportional to the current flowing through the primary winding of the power transformer.
