    Abstract: A power factor corrector (PFC), such as for an on-board charger (OBC) for charging a vehicle traction battery, uses an input voltage and an input current from a power source to output a desired voltage. The PFC has an inductor and first and second power switches. A micro-controller generates, for each half-cycle of the input voltage, first and second reference signals respectively indicative of (i) a sinusoidal envelope of the inductor current for which the PFC will absorb sufficient power from the power source for the PFC to output the desired voltage and (ii) a reverse value of the inductor current for which zero voltage switching (ZVS) of the switches is ensured. A comparator assembly turns the first switch off (on) and the second switch on (off) upon the inductor current equaling the outer sinusoidal amplitude envelope (the reverse value) whereby the PFC outputs the desired voltage with ZVS.

  • Patent number: 10601333
    Abstract: An isolated switched-mode power converter converts power from an input source into power for an output load. Power switches within a primary-side power stage control the amount of power input to the power converter and, ultimately, provided to the output load. A digital controller on the secondary side of the power converter generates signals to control the power switches. This generation is based upon closed-loop (feedback) control as well as feedforward control. The feedforward control compensates for variations in the voltage of the input source. The input voltage is estimated by sensing a rectified voltage at a node between a secondary winding of the isolation transformer and an output filter. The feedforward compensation modifies the generated switch control signals based upon the sensed rectified voltage.
