Abstract: A power factor correction controller is utilized for a power factor correction circuit in a critical conduction mode of an electric power converter. The power factor correction controller generates a control voltage according to an output voltage outputted from the electric power converter, and utilizes a first threshold value to detect the control voltage. The power factor correction controller can control the power factor correction circuit to operate in different modes according to various levels of a load. Therefore, an objective according to the present invention for reducing electric power consumption of the electric power converter in a light load or a no-load mode and improving energy transmission efficiency can be attained.

Abstract: A method for controlling operation of a resonant converter is to be implemented by a control module that generates a drive signal for controlling a power switch of the resonant converter to thereby control an output voltage and an output current provided by the resonant converter to a load. The method includes: (A) configuring the control module to determine if the load is operating in a first mode or a second mode; (B) configuring the control module to generate the drive signal according to the output voltage when the control module determines that the load is operating in the first mode; and (C) configuring the control module to generate the drive signal according to the output current when the control module determines that the load is operating in the second mode.
