Beschreibung
Zusammenfassung:A power converter system may include a first power converter configured to couple via its input to a power source and configured to convert an input voltage provided by the power source to an intermediate voltage, a second power converter coupled via its input to an output of the first power converter and configured to convert the intermediate voltage to a regulated output voltage, a capacitor coupled at one of its terminals to an electrical node of the intermediate voltage. Based on one or more electrical parameters of the power converter, the second power converter is controlled to regulate the regulated output voltage at a substantially constant level and the first power converter is controlled to control the intermediate voltage to maintain the intermediate voltage between a maximum voltage and a minimum voltage and regulate an input current drawn from the power source at a substantially constant level.
