Abstract
A switching power supply is provided which includes an input for an input current at an input voltage, a controlled transistor bridge having two branches each with two transistors, the two branches being connected in parallel to the input terminals, a transformer having a primary connected between the midpoints of the two branches formed between the transistors of each branch, an output for an output current connected to the terminals of a secondary circuit of the transformer, and a control unit for the transistors to alternately switch each of the midpoints between high and low values with a time offset between the switching times of the midpoint values. The control unit is also capable of ensuring that the time order for switching of the midpoints between the high and low values thereof varies over the course of time.
