Replaced the unshielded inductors with shielded ones. Increased the switching frequency, which allows for smaller filter capacitance and a better power factor under light load. Power factor and efficiency at max load are unchanged. Layer order for high voltage planes was modified to reduce parasitic capacitance on the flyback traces and voltage stress on the board dielectric.
