An economical single-phase passive power-factor-corrected rectifier: topology, operation, extensions, and design for compliance

This paper describes a novel passive power-factor correction circuit that ensures the compliance of the capacitively filtered single-phase rectifier with the EN61000-3-2 norm at a cost much lower than the known solutions. The circuit can be used to about 300 W. The additional components are a small inductor, a small capacitor and a diode.
