Abstract: A power supply includes a controller. The controller controls switching of a first switch and a second switch in a power supply to regulate conveyance of energy from a primary winding of a transformer to a secondary winding of the transformer to generate an output voltage. To control generation of the output voltage, the controller receives a first signal generated at a first node coupling the first switch and the second switch. As discussed herein, the controller controls activation of the first switch to an ON state depending on a magnitude of the first signal. This disclosure provides improved reliability of power supply components (such as one or more switches) because such components are no longer stressed (or overstressed) due to body diode cross conduction.

The second DC discharge circuit is operative to receive a DC discharge current from the first DC discharge circuit; logic associated with the AC/DC converter repeatedly: receives a DC sense signal from the second DC discharge circuit and determines, based on the value of the DC sense signal within a predetermined measurement time period, loss of the AC input signal. In response to determining loss of the AC input signal, the logic controls activation of the second DC discharge circuit depending on the DC sense signal.

Abstract: A power supply as described herein includes a voltage converter, main controller, and a bias controller. The voltage converter including a primary stage and a secondary stage. The controller is operable to control regulation of an output voltage from the secondary stage based on a received feedback signal. As its name suggests, the output voltage from the secondary stage powers a load. During certain load conditions, the bias controller maintains (via novel biasing) a magnitude of a power supply voltage above a bias threshold value. More specifically, the bias controller is operable to prevent the power supply voltage from falling below the bias threshold value, preventing an under voltage lockout condition such that the controller is able to quickly continue conveyance of sufficient energy from the first stage to the second stage when the load increases a rate of consuming power provided by the output voltage.
