Abstract
An AC input power converter comprising a rectifier circuit (D, D, D, D) for rectifying an AC input signal, a first unidirectional device (D) coupled in series with a first capacitor (C) for charging the first capacitor (C) and wherein the first unidirectional device (D) and the first capacitor (C) are arranged in parallel to an output of the rectifier circuit (D, D, D, D), a second unidirectional device (D) coupled in series with a second capacitor (C) for charging the second capacitor (C) and wherein the second unidirectional device (D) and the second capacitor (C) are arranged in parallel to an output of the rectifier circuit (DD, D, D), a first output (OUT) for providing a first power and a first average voltage to a first power converter, wherein the first output (OUT) s coupled to a first node between the first capacitor (C) and the first unidirectional device (D) and a second output (OUT) for providing a second power and a second average voltage to a second power converter, wherein the second output (OUT) is coupled to a second node between the second capacitor (C) and the second unidirectional device (D), wherein the first capacitor (C) has a first value and the second capacitor (C) has a second value, and wherein the first value of the first capacitor and the second value of the second capacitor are selected such that when the first power is lower than the second power, the first average voltage is larger than the second average voltage, and when the first power is larger than the second power, the first average voltage is lower than the second average voltage.
