Abstract:
1. A power converter, comprising: an input circuit having a rectifier configured for receiving a full-wave AC signal along a first conductive path and a second conductive path, the rectifier including a single diode rectifier and a filter that includes an inrush resistor, a coil, an electrolytic capacitor, and a non-electrolytic capacitor connected in series with the rectifier, the coil connected in series with the non-electrolytic capacitor and arranged to extend the second conductive path to common, and the filter providing a DC voltage output at a circuit node connecting the inrush resistor and one electrode of the electrolytic capacitor, and wherein the coil and the inrush resistor are connected in parallel between the non-electrolytic capacitor and the electrolytic capacitor, and a switched mode power supply IC arranged to receive the DC voltage output from the filter.
