Abstract
The invention is directed to a switching power supply with a primary switched-mode direct-current converter, in which the conductivity of a transistor (2) driving the base of a switching transistor (1) is operated on by the sum of two control signals. The sum of these control signals is generated by two low-resistance voltage sources in series arrangement, the sources being proportional to the emitter current and the input voltage, respectively.
