Abstract
A bridgeless power factor correction (PFC) control circuit includes a non-linear current sensor. The non-linear current sensor includes a non-linear shunt, a comparator, and a reference voltage circuit. The non-linear shunt includes a capacitor connection terminal and a ground terminal. The comparator includes a first input, a reference voltage input, and a zero-crossing detector output. The first is input coupled to the capacitor connection terminal. The reference voltage circuit is coupled to the reference voltage input.
