1. An asymmetric power converter, comprising:
a primary-side rectifying/filtering circuit, configured to receive an input voltage, and rectify and filter the input voltage into a first voltage,
a power factor correction circuit, configured to receive the first voltage, and convert the first voltage into a power voltage,
an asymmetric conversion circuit, configured to receive the power voltage, and convert the power voltage into an output voltage to supply power to a load, and an output current being drawn by the load,
a feedback control circuit, coupled to the asymmetric conversion circuit, and configured to generate a feedback control signal according to a load power demand provided by the load, wherein the load power demand comprises information of the output voltage and information of the output current,
wherein the feedback control circuit controls the asymmetric conversion circuit to operate in a full-bridge resonant mode, a half-bridge resonant mode, or a hybrid half-bridge resonant mode according to the feedback control signal.
