Abstract
Examples are disclosed that relate to a power supply device having improved power efficiency. In one example, a power supply device includes an electrical power interface configured to receive electrical power from a power source. A power factor correction (PFC) circuit is configured to increase a voltage of the electrical power from an input voltage to a converter voltage and increase a power factor of the power supply device. An LLC resonant converter is configured to regulate an output voltage based at least on the input voltage and a system load. A voltage boosting circuit is configured to turn off the PFC circuit and increase the voltage of the electrical power from the input voltage to the converter voltage based at least on an operating condition of the power supply device.
