Abstract: A disclosed power supply includes a power factor correction circuit including a switch, an inductor having a first terminal connected to an input voltage, and a second terminal connected to the switch, a storage capacitor and a load, a value of the inductor selected to operate the power factor correction circuit in discontinuous conduction mode, and a controller programmed to operate the switch to increase a power factor of the power supply. The switching frequency of the switch is periodically adjusted to reduce electromagnetic interference.
