Patent ID: 6987678

Claim:
A switch mode power supply for supplying an output voltage and current to a load, comprising: a transformer including a primary winding and a secondary winding; a primary circuit comprising a switching stage electrically coupled to the primary winding of the transformer; and a secondary circuit connected to the secondary winding of the transformer, wherein the secondary circuit comprises a rectifier circuit electrically coupled on an input side to the secondary winding, the rectifier circuit providing a rectified output voltage to a storage capacitor, and an output circuit including a switching device electrically connected on one side of the switching device to the rectifier circuit and on another side of the switching device to one side of an output capacitor, an output terminal and an input of a voltage sensing and control circuit, and the voltage sensing and control circuit providing an output that controls switching of the switching device such that the output voltage is regulated, further wherein the output circuit does not comprise an inductor.
