Abstract
A switch mode power supply comprises a power converter including a transformer having a primary winding connected to a primary circuit, and a secondary winding connected to a secondary circuit delivering an output voltage to a load. The primary circuit comprises a controller for operating a switch element to chop the current flowing in the primary winding to transfer energy selectively to the secondary winding. The secondary circuit comprises a storage capacitor delivering the energy to the load, a first regulator receiving the output voltage and delivering a first control current for the controller via an isolator element, and a second regulator receiving an auxiliary output voltage that is an image of the output voltage and delivering a second control current for the controller. The second control current is added to the first control current to avoid any interruption in the chopping of the current flowing in the primary winding.
