Abstract:
A DC/DC converter controlled by a rectangular signal, comprising:an input for a source of direct voltage; a transformer comprising a primary winding connected to the source of direct voltage, a secondary winding connected to an output of the DC/DC converter, and a tertiary winding located in proximity to the primary winding and the secondary winding on a core of the transformer, wherein the tertiary winding has a direction of winding that is the same as a direction of winding of the primary winding, and wherein a terminal of the primary winding and a terminal of the tertiary winding are identically biased and coupled to a first terminal of the source of direct voltage; a controllable switch connected in series with the primary winding and the input of the source of direct voltage; a first diode and a second diode, the diodes connected in series with the tertiary winding and in a blocking direction with respect to the source of direct voltage; and a magnetic reversal capacitor for resetting the transformer.
