Abstract:
Systems, methods, and apparatus for a circuit with power factor correction (PFC) are disclosed. In one or more embodiments, the disclosed method comprises providing, by a single-stage power converter, a delay in phase between a peak current command and a rectified input voltage such that a phase of a transformer current intentionally lags behind a phase of the rectified input voltage to maintain a power factor (PF) level and a total harmonic distortion (THD) level for the single-stage power converter. In one or more analog embodiments, a resistor and a capacitor are implemented into a conventional single-stage power converter to provide the delay in phase between the peak current command and the rectified input voltage. In one or more digital embodiments, a controller within a conventional single-stage power converter exclusively provides the delay in phase between the peak current command and the rectified input voltage.

Claim (Index 1):
A method for a switching power converter, comprising:\n filtering a rectified voltage and a rectified current through an electromagnetic interference (EMI) capacitor to produce an input current and an input voltage for the switching power converter, wherein filtering the rectified current through the EMI capacitor produces a capacitor current through the EMI capacitor, and wherein a phase of the capacitor current leads a phase of the input voltage; and delaying a phase of an inductor current for the switching power converter to lag a phase of the input voltage to compensate for the capacitor current so as to increase a power factor for the flyback converter.
