    Abstract: The disclosed embodiments provide a system which starts up and shuts down a resonant oscillator circuit. During the start up process, a driving circuit uses a first clock signal to control a first phase output of the resonant oscillator circuit. At the same time, the driving circuit uses a second clock signal to control a second phase output of the resonant oscillator circuit, wherein the first and second clock signals have opposite phases. While the first and second phase outputs are being controlled, the system ramps up an input voltage, which is used to power the resonant oscillator circuit, wherein the ramping takes place across multiple initial oscillation periods. During the shut down process, the system shuts down the resonant oscillator circuit by ramping down the input voltage. After the input voltage has been ramped down, the system clamps the first and second phase outputs to a fixed voltage.

    Abstract: The disclosed embodiments provide a system that operates a power supply. During operation, the system disposes a first switching mechanism between a first output of a first power converter and two or more loads. Next, the system obtains two or more error signals for the two or more loads, wherein each error signal from the two or more error signals represents a difference between a load voltage of a load from the two or more loads and a first reference voltage for the load from a first set of reference voltages for driving the two or more loads using the first power converter. The system then uses the first switching mechanism to couple the load with a largest error signal from the two or more error signals to the first output. The disclosed embodiments also provide a system that operates a power supply. During operation, the system obtains power states of two or more loads coupled to two or more power converters in the power supply. Next, the system generates one or more control signals for a set of switching mechanisms to configure a coupling of the two or more loads to the two or more power converters through the switching mechanisms based on the power states.
