Abstract
A power factor correction (PFC) pre-converter includes a boost converter and a PFC controller. The boost converter is configured to step up a boost converter input voltage by generating a boost converter output voltage. The boost converter includes an inductor, a switch, and a diode. The PFC controller is configured to control the switch by generating a signal causing the switch to be closed for a first period of time. The first period of time ends when current through the inductor reaches a target current value. The PFC controller is also configured to control the switch by, in response to the first period of time ending, generating a signal causing the switch to be open for a second period of time. The second period of time is based on a ratio between the first period of time and a critical conduction mode on time.
