摘要： According to one configuration, a power system includes a resonant power converter, a monitor resource, and a controller. During operation, the resonant power converter converts an input voltage to an output voltage. The monitor resource monitors a magnitude of the input voltage. The controller dynamically controls a corresponding resonant frequency of the resonant power converter and a switching frequency of switches in the resonant power converter depending on a magnitude of the input voltage.

摘要： In accordance with an embodiment of the present invention, a method of controlling current through a transistor includes measuring a voltage across the transistor, measuring a current through the transistor, determining a safe operating current for the measured voltage across the transistor, and adjusting a voltage of a control node of the transistor using a feedback controller until the measured current through the transistor is not greater than the determined safe operating current.

摘要： A multi-level converter comprises one or more flying capacitors configured to operate at balanced voltages. The multi-level converter comprises a plurality of switching groups comprising pairs of switches operable to transfer energy to and from an inductor and the one or more flying capacitors for inverting an input voltage to an inverted output voltage. The multi-level converter comprises the inductor configured to operate according to an inductor frequency greater than a switching frequency used to control the plurality of switching groups.
