Abstract: An apparatus such as a power supply includes management hardware. The management hardware monitors operation of multiple power converter phases coupled in parallel to produce an output voltage. Based on the monitored operation, the management hardware determines a status of a series circuit path connecting windings of the multiple power converter phases. The management hardware produces status information indicating the status of the series circuit path.

Abstract: A power supply includes a storage component to store an output current value representative of a magnitude of output current supplied by an output voltage of a power converter to power a load. The power supply further includes an offset reference generator and a controller. The offset reference generator produces an offset reference signal, the output current value being offset by the offset reference signal. The controller controls generation of the output voltage of the power converter as a function of the offset output current value with respect to a threshold signal (value). Additionally, the controller is configured to detect a startup mode of a power converter operative to convert an input voltage into an output voltage. During the startup mode, the controller: i) produces a threshold signal having a magnitude that varies over time, and ii) controls operation of switches in the power converter as a function of the threshold signal while the power converter is operated in a diode emulation mode. Implementation of the startup mode monotonically increases a magnitude of the output voltage without dips.

Abstract: In one implementation, a power converter with over-voltage protection includes a power switch coupled to a power supply through a tank circuit, and a control circuit coupled to a gate of the power switch. The control circuit is configured to turn the power switch OFF based on a current from the tank circuit, thereby providing the over-voltage protection to the power converter. In one implementation, the power converter is a class-E power converter. In one implementation, the control circuit is configured to sense the current from the tank circuit based on a voltage drop across a sense resistor coupled to the power switch.
